Walk Out of Life

It seems, more so lately than before, have I noticed people who give ultimatums for friendship.  Why does everyone you know have to be your best friend?  If not your best friend, than close friend?  Why can't there be acquaintances?  Maybe this is the loophole in my relationships with friends showing and I just can't keep anyone close unless they are willing to make more of the effort.  So, for those of you who have decided to be friends or "not friends" (which includes enemies, but in my book acquaintances are perfectly fine), feel free to define our relationship because if you won't fight for it, why should I?

If you want to walk out of my life, 

I'll hold the door for you."
