Excellent Farkel.
I have always found that when I share things about myself, the person I am talking to, will generally do the same. If they don't, it feels odd, and that person will not become a close friend.
For some reason, people tell me the damndest things about themselves..............I must have something they sense, that tells them to talk to me. I have always been a very open person, and don't hide things.................I think that is part of it. I know how to listen and commiserate. I think most women are that way, though.
An old cliche "to have friends, you have to be a friend". Very true.
