There are a lot of them...
But one of the differences is that men socialize by insulting each other:
"Hey Harry, you old idiot!, How are you doing?
Cheating on your income tax as ever?"
They don't mean it
Women socialize by complimenting each other:
"Sally, sweetheart, that adorable sweater is definitely your colour!
We need to get together for lunch sometime."
Women don't mean it either
