You can have friendships of all types. I have some friends that are too BROey for me at times where I have to spread some distance from them; hence my comment about Deftones at Coachella being a bro-show. Guy has a good heart, but jesus, when he starts to talk all "Chicks bro and smoke me out bro, I'm soooo broke" I take a vacation.
Then you've got the friends who are such intellectuals about everything, you just want to slap them and say - HEY drink this beer, smoke this joint and don't give a fuck for a whole 5 minutes! -
A friend is someone who will be there and can chill with you, doesn't care where you are financially (for the basis of friendship); someone you can vent to who will understand your need to vent (you'll be able to do the same for them) and you can always pick it up where you left it off, even if you haven't seen each other for a good minute.
Then sometimes you just have history with people where throwing things down the garbage disposal because they said something stupid on facebook is a bit of an over reaction.
I enjoy all my circles of friendship and glad I'm not a bitter cynic, just a cynic.
