Friend- one attached to another by respect or affection, one who one knows, likes and trust. Many people use the term friend too freely. I think people confuse acquaintances for friends. Friends are supposed to be someone real close to you. If you have more friends then you can count on both hands than you might need to re-evaluate the meaning of the word friend.
Hov said it best "you never know who your true friends are til yall both got a lil bit of money. I mean cuz yall both broke there is no strain on the relationship, yall both broke. And if you got money and he aint got no paper, he still need you so you never know how he feel about you. When yall both get some paper you'll see." Basically he saying niggas only wanna be around when they can use you as a crutch. But I feel that's only fake people, real people stay around even after they get on there feet so maybe one day they could be your crutch. The circle that you call friends, are the just around to use you as a crutch or would they help you when your down too.
