It is so true what has been said in this thread. Sadly, friendship among JW's seems to be 'conditional' and grows or fades with one's own growing or fading in the 'truth'.
There are a few people in the KH where I go whom I hold very dear. But there is always the thought in the back of my head that, should I mess up (which I am in the process of doing), they will not consider me a friend anymore. Although many have not been a friend to me because I'm the eternal bible student who never gets around to jump in the pool for baptism, I have been a friend to as many people as I could. That includes taking other people's children on my lap and entertain them when they are fussy, calling the elderly members of the congregation to make sure they have a ride to the KH, buying lunch after the meetings for families I know cannot afford to go out for a bite to eat, etc.. etc..
I can relate to one of the above posts where was mentioned that the worldly friends remain friends when one decides to join the JW's, but the JW friends do not usually remain friends when one decides to leave the JW's.
