I'd like to posit that that's bullshit.
Well, it's half true. You don't have to be lumped with friends you don't like. But you can't necessarily choose that a particular person will be your friend and have it come true.
Sure, you can add them on a social networking site and get all excited if they add you back and leave a few comments, but fully-fledged friendships are part choice, part chance, and part reciprocity.
On a completely unrelated note: what sort of crackpot name is "Biz", anyway?
