A friend is someone who will catch you when you fall, dry your tears and tell you it will be all right, pretend to be happy just to cheer you up, never leave you by yourself, attempt to talk to you at least once a day no matter what, make you laugh when you're sad, call back if you hang up on them, make everything you two do together into something fun no matter how boring it is, always remind you of your inside jokes, finish your sentences, think the same way you do, follow you wherever you go, stop you from doing something stupid or hurting yourself, and they're always willing to give up something that means a lot to them because they can be sure you'll always be there in return, and because to them you'll always mean more than you can imagine.
