In one sentence, describe what the following article is about: Regardless of the type of event you're inviting your guests to, you should use a formal writing style on a formal invitation. This means spelling out dates and other words that are usually abbreviated. For example, you should write "Saturday, the nineteenth of November" instead of "Saturday, November 19th." You should also write "253212 Boston Street" instead of "253212 Boston St." Don't use the shortened versions of guests' names. Write "Stephanie Smith" instead of "Steph Smith" and always use last names. One of the most important parts of the formal invitation is the inclusion of the event's host(s). Listing the hosts tells your guests who is inviting them to the event. How you write the hosts' names and the order in which you should list them varies depending on who is hosting. These rules are particularly important if you are writing a formal wedding invitation. For example, you should start a dinner invitation by saying "Sam and Ellen Smith invite you to a dinner celebrating the graduation of their daughter Leslie from graduate school."
Summary: Write out dates. Write out guests' full names. Include the hosts.

In one sentence, describe what the following article is about: Since backpacks can feel heavier the longer you wear them, find a pack with padded straps. Look for bags that have thick, breathable pads on the straps so you don't get too warm while you're carrying it. Try on the bag and carry it around to see if the pads are comfortable on your shoulders. If possible, get a bag with hip straps to help take some of the weight off of your shoulders. Look for backpacks that are made of durable materials, such as high-quality nylon or polyester, so your bag doesn't break. Check the zippers and straps to make sure the seams are sewn tightly since they are the first areas to usually break. Look at the packaging to see what the bag is made of so you know what to expect from your bag. Make sure the backpack is waterproof so your things don't get wet. If your bag isn't waterproof, you can always buy a rain shield to cover your backpack. Some backpacks may have a lightweight frame to maintain the structure of your bag. The back panel is the part of the bag that rests against your body and adds support. Look for bags that have a curved back panel rather than a flat one so it fits comfortably on your back. Make sure the back panel has ventilated foam or is made of breathable material so you don't get sweaty while you're carrying your backpack. Many back panels also have a carrying strap so you can put your bag on the handles of your other luggage. Some specialty bags may have a storage compartment in the back panel. Some travel backpacks have wheels on the bottom so you don't always have to carry them on your back. Get a wheeled backpack if you want to comfortably travel with it and take the weight off of your shoulders. These backpacks also usually have front-loading zippers so your things are easy to access. Rolling backpacks may take up more space and weigh more due to their wheels.
Summary: Get a backpack with comfortable padded straps for the best support. Choose a light and durable backpack so it lasts for a long time. Find a backpack with an ergonomic, ventilated back panel. Use a wheeled travel backpack to make transporting the bag easier.

In one sentence, describe what the following article is about: Gently take off any clothes or jewelry near the burned skin. Try not to pull clothes over the burned area to keep from irritating your skin further. Turn the faucet on so the stream of water is gentle rather than strong. Rinse the burned area under the cool running water to remove any traces of vinegar and soothe your inflamed skin. Do not rub or scrub your burn as you rinse. Avoid using soap on your burn. Remove your glasses or contact lenses if you've gotten vinegar in your eyes. Blink your eyes under a gentle stream of room-temperature water for 20 minutes. If your child has gotten vinegar in their eyes, gently pour the water over the bridge of their nose and encourage blinking. Then, flush their eyes with room-temperature water for 20 minutes in a tub, shower or sink. Use only clean, fresh water to cleanse burns. Other liquids may further irritate burned skin rather than soothing it.
Summary:
Remove clothing or jewelry that has vinegar on it. Run the burn under cool running water for 20 minutes. Rinse your eyes for 20 minutes with room-temperature water. Avoid using milk or other liquids to flush a burn.
