Have name changed as I know a few of these. Slightly light-hearted and of course a generalisation, but I do wonder. I mean, don't they need to be a bit hard and a little two faced just to get through growing up in a family of girls?
I can think of 2 women in particular, acquaintances, who both have 3 sisters and no brothers. Both are fickle, have an out of sight out of mind attitude to friends and talk about things that their friends have clearly told them in confidence to others.
I have kept a distance, for my own self-preservation. But I just wondered whether anyone else has ever found this.
