What attributes do you like them to have? What makes you want to keep them in your life? What interests you about them?
I've just been reading another thread where one poster said she only has friends who make her "feel good" but how do your friends make you feel good?
I've let a lot of long term friendships drift this year and it's been a strange few months. I'm interested to know what people's standards are friendship wise because to be honest I'm cutting off that many people at the minute I'm starting to think it's me and I'm the shit friend!
