Body language says a lot about how you feel about someone. Showing the guy you don't like him through your body language can sometimes get him to back off, even if it takes him a while to get the hint. It may not make him stop liking you instantly, but he'll learn that he's not going to get anywhere with you. Turn your body away from him, as that's a physical indicator that you don't like him. Also, cross your arms around him. You could also frown at him, as that will indicate you're not interested. When you're attracted to someone, you tend to want to talk to him and tell stories about yourself; therefore, when you talk a lot to someone you don't like much, it may give him the wrong impression. If you're too talkative, it can seem like you have an interest in him. Keep any conversations you need to have with him short and to the point. If you see this person at school or work, make sure to only talk to him when necessary. Laughing at someone's jokes is a way to show him that you like him. If you're trying to get him to understand that he shouldn't be interested in you, skip laughing at his jokes. If you laugh and smile at him, he may take that as encouragement. In the same vein as avoiding being too talkative, making sure you're around him as little as possible can also get the message across. If you try to avoid seeing him or reject any plans he tries to make with you, he should eventually get the idea that you're not interested and he shouldn't stay interested in you. Sometimes, a way to avoid interacting with someone is to make sure you're not alone very often. Keep your friends close, or try to find a way to strike up a conversation with someone else if you see him coming. He should get the message you don't want to talk to him. If he's sending you too many messages or invading your digital space (after you've told him not to), block him. You have a right to not be harassed. Block his number on your phone, and block him on the social media platforms that you use. It should send a clear message that he needs to back out of your life. Push him away if he gets close, and firmly tell him "no." If you keep letting him back in and then pushing him away again, it's only going to muddy the waters. If you don't want him to be interested, make sure you are consistent in telling him "no."

Your bandage should still be on your tattoo for at least two hours after you received it. Of course, that time varies and you should do as you were instructed by your tattoo artist. When you finally do remove your bandage, make sure to take it off with care. If your bandage is so tight that it sticks to your tattoo, then you should use running water to loosen the covering. Let the water drip gently upon the bandage until you feel the adhesive lose its grip. Once it is loose, gently take the bandage off. Scabs develop over a tattoo in order to protect it from germs. Though they may irritate you, you should not pick at the scabs that cover your tattoo. If you pick at them, then you risk the chance of getting an infection. This is dangerous and can also ruin the tattoo's design. You might accidentally knock off one of your scabs. If it was just a small scab, you shouldn't worry too much because you probably haven't lost a lot of ink. If it's a bigger scab, then you might have to get it retouched in time. Put a dab of cleaning solution or soap on your tattoo. Rub the area with your hand. After you do this, use water to rinse your tattoo. If you feel a slippery substance, then you probably are encountering plasma. Dried plasma will cause you discomfort, therefore you should rinse your tattoo until you remove all of it. After you have rinsed your tattoo, dab at it with a clean towel. Do not use soap with dyes or scents. A mild soap is best. You may be tempted to dip your feet into a tub of warm water after your tattoo. Don't do this. Soaking your feet will not only create the perfect situation for a bacterial infection, but it will also cause the ink to run. For the first three weeks, you should avoid swimming. If you swim regularly, you should try to avoid swimming for the time it takes your tattoo to heal. Rub anti-bacterial ointment or lotion over the tattooed area. Use a paper towel to remove the excess ointment or lotion. You should use an unscented lotion such as Lubiderm or Aveeno. You do not need to use a foot-specific lotion. In fact, you should try to avoid specialty lotions and creams, they may not work as well as advertised when it comes to tattoo care. Do not use too much moisturizer. If you do this, then you run the risk of removing some of your tattoo's ink. Do not use petroleum jelly. This will cause your tattoo to lose ink.
