It's a drag. No one dreams of doing so. But if you're lucky enough to get the experience, here are some tips:
1. Talk to random people. It actually works. You've probably been told this so many times, but just benefit from it and TRY IT.
2. Be yourself, because no one likes plastic.
3. If you're about to get a new friend, don't give up on it. You've worked your way to that point, and you might as well continue with it.
4. Find something to talk about, like holidays, recent quizzes, even people if you're really desperate. It's better than being that quiet freak with no friends (Living proof is the author of this.)
5. Don't be a bad person. People don't really like that.
