Friends

No matter where you are or what you do, you need to make some friends. If you don't, you will start to slowly deteriorate into insanity. Good friends will stick with you, usually no matter what you do. Even if they don't, and for some reason you cease to be friends, there are billions more to find and befriend. Having a lot of friends is both a good and bad thing. It is good because no matter what, you would always have someone to converse with. However, no matter how hard you try, or how nice you are, you will have people who hate you. That is how the system works, things will always balance out.
