Friends friends friends...which are good...which are bad?

The stock market isn't run by greed, it's run by friends and connections. Ok that's not true, but this is kinda my take on friends and such. I'm really the kind of friend who wants to spend a lot of time with another friend if we have the time. However I'm also the kind of friend who wants time alone....really alone. The fact is, when friends and I dont' see each other for a long time or make me feel left out (or vice versa) don't really feel bad. I'm the type of person who nudgingly thinks of all my past friends in my mind. Basically dont' feel bad that you guys need an actual "life" that doesn't involve me, since I'll cherish the moments that we get together anyways.
