Miss Mango, I think you missed Tully's joke
He's a subtle one.
One of the clear differences I see between the sexes on a daily basis in my work with small children is that at ages 5-6, boys are better with concrete thinking and things they can put their hands on, while girls are better at abstract thinking. This difference becomes less pronounced as kids get older; boys start catching up at 6-7 in abstract thinking, and vice-versa.
Another difference--and this one is a gender difference--I see in adults that troubles me is how young men in particular seem petrified to ask for help, especially when it comes to mental health/mental issues. Women seem to be more comfortable with that, though I'm sure as with all things, there are exceptions. I think that the construct of gender is partially responsible for this.
