I have 4 really really close friends I can tell anything to, I've known then my whole life.
And 6-7 other friends I hang around a lot and trust them at a certain point.
My other "friends" are just random people to me. I don't like them but I have to go to school to them everyday or their parents hang out with my parents so I have to do it, even though my parents know I can't stand every each of them.
