If you plan on refilling your empty water bottle to drink from it again, using a BPA-free bottle is your safest bet. Water bottles are made from a variety of plastics, and these plastics, like BPA, can leach. Exposure to BPA has been linked with diabetes and cardiovascular disease in humans. A more suitable alternative for a refillable water bottle would be a stainless steel or glass bottle. These do not leach. A bottle meant for reuse will typically have a wide opening that will allow you to clean the bottle easily. Refrain from drinking from a refilled, disposable plastic water bottle. Disposable plastic bottles are hard to clean, so they can easily host bacterial growth. They also contain chemicals which could cause cancer or reproductive health problems. You should use hot soapy water to clean your bottle. Do this at least every two days to minimize bacterial contamination. As long as you clean your bottle, you should not have to worry about chemicals from a non-BPA bottle leaching into your water. Let your bottle air dry. You can also use a dishwasher to dry your refillable water bottle as long as the bottle does not contain BPA, since heat will increase the rate at which chemicals leach from the plastic.

Summary: Use a BPA-free bottle. Determine whether your bottle was meant for reuse. Wash your bottle thoroughly. Dry your bottle.

Plastic food bowls can cause eye irritation due to tiny cracks that build up bacteria. If you use plastic bowls, try switching them out for glass, stainless steel, or porcelain bowls. This small tweak may lead to fewer tear stains in your dog or cat. The high mineral content in some tap water can cause irritation in cats and dogs, leading to tear stains. If your pet is prone to tear stains, try switching from tap water to bottled water. This may make a difference in the appearance of tear stains. If you have a filtration system such as a Brita filter, try using that instead. Longhaired dogs are particularly prone to tear stains as their fur irritates their eyes. Long hairs around the face can easily brush against the eyes, leading to tearing and irritation. Regular trimming can help combat this problem, so make regular appointments with your groomer. Unless you have specialized training in pet grooming, it is not advisable to attempt to trim your dog's face yourself. When trimming near a dog's eyes, it's very easy to accidentally clip into your dog's face or eyes. Always consult a professional. While there is no clear link, a high quality diet can prevent health problems overall. If other means have not helped with tear stains, have a talk with your vet about your animal's current diet. They may recommend switching food types (i.e., switching from wet food to dry food) or trying a more nutritious brand of cat or dog food. Switches in food type should usually be made gradually to avoid stomach irritation. Talk to a vet about how to slowly introduce new foods to your pets to prevent indigestion.

Summary: Switch your food bowls. Use bottled water. Have longhaired dogs trimmed regularly. Talk to your vet about high quality food.

Your squad is there to help you have fun, but being part of the group also means looking out for one another. Watch each other's backs and drinks. When a girlfriend starts to get a little too drunk, cut her off. She may be upset with you, but she'll thank you in the morning. If a creepy guy won't leave your girlfriend alone, tell him to take a hike. Make sure each of you gets home safely when the night is over. If you live in a place without good public transportation, having a designated driver can literally save your life. Party girls are all about fun. Sexually transmitted diseases and unwanted pregnancies are decidedly not fun. Making out with a guy you just met can be fun, but be careful who you decide to sleep with. Always make sure your partner wears a condom. Be sure that it's not a "natural" or "lambskin" condom, as these do not protect against HIV. Remember that sex always carries some risk. Condoms can always break. There is no such thing as completely safe sex, only safer sex. Most party girls drink alcohol as part of having fun, but you shouldn't overdo it. Don't drink past your limits. You don't want a fun night on the town to ruin your health. Avoid drinking if you are under the legal age to buy alcohol. Don't give in to peer pressure even if all of your friends drink. Never drive drunk. Drugs can be a big part of many party scenes, and some party girls like to partake. These substances can be harmful by themselves, but they may also include unknown and deadly impurities. Don't take any pills offered to you at a party.

Summary: Party with friends. Practice safe sex. Drink responsibly. Don't do illegal drugs.

If she knows that the Warriors are your favorite basketball team and has suddenly started talking to you about them, then she may have picked up a new love for the team just because of you. If she knows you love watching Game of Thrones and suddenly knows everything about the characters, then she may just be trying to impress you with these new interests. If she's never shown an interest in your interests before but suddenly seems to know everything about the things you like, then she probably likes you. If she approaches you and asks a question that you know she can easily get answered by someone else, like how hard the math test was, or what new sport you played in gym class, then she's clearly just looking for an excuse to talk to you. If she asks what you think of a certain teacher or the new kid in school, she's just trying to spend more time with you by asking any question that comes to her mind. If the girl teases you, then it's almost definitely true that she likes you. If she makes fun of you, from laughing at your shoes, giggling at your new outfit, or makes a comment about how messy your locker is, then she's just teasing you because she likes to be around you. Sometimes, her teasing can even get a little mean, but that doesn't mean she doesn't like you. Just remember the golden rule: if she's paying attention to you, she likes you. Teasing is just one way of paying attention. In middle school, teasing and flirting are almost interchangeable. Still, there are some signs that the girl is flirting with you. If she winks at you, even jokingly, she's definitely flirting. If she teases you about your new haircut and maybe even says it's an improvement, then she's flirting with you. If she acts coy, playful, or just a little bit silly around you, then she's flirting with you. If she makes fun of you for liking another girl, especially when you clearly don't like another girl, then she's just flirting with you. If the girl is suddenly interested in who you like and if you want to ask any girl out, then she wants to know if you like her -- unless she's playing matchmaker for one of her friends. If she's always bugging you about who you like or even throws out some names of people she knows you don't really like, then she's just trying to talk to you about your romantic life to get close to you. If she makes fun of any girlfriends you've had in the past, or just makes fun of other girls around you, then she's probably just jealous because she really likes you. Middle school girls love flirting over Facebook and texting. Remember the first rule: if she pays attention to you, then there's a good chance she likes you. If she's always texting you or posting on your Facebook wall for no reason, then she probably likes you. If she posts a video or a link to something you like on your Facebook wall, then it's even more likely that she likes you. If she asks what you're doing over the weekend when she texts you, then she's interested in you plans because she likes you. Check out her Facebook activity. Does she talk to other guys on Facebook as often as she talks to you, or are you special?
Summary: See if she tries to talk about common interests. See if she looks for any excuse to talk to you. See if she teases you. See if she flirts with you. See if she asks who you like. Notice what she says to you over Facebook or texting.
