so when my man comes home from the pub -

[cardi88]

asking me - am i really like this, am i really like that, its because men rib each other relentlesley - just seen the three 'blokes' chatting now and all they do is wind each other up, put each other down and in a way make try to insecure each other, why do men do that? when us girls get together what do we talk about?!!

We talk about feelings, men, other people we know and are generally supportive of each other, and empathic. That's what women are like! Men are too MANLY to be like that when with each other. They need to reinforce their MANLINESS around each other, so never dig too deep, and make each other laugh at each others expense.
Why? Let's ask a psychologist to answer that one!
