I have to wonder, that's for sure. It was part of my job in the Navy to be able to read maps. I worked with them all the time.
It may be a lack of interest in such things more than anything else. But, hey! I'm just a chick, so what do I know? LOL!
I do know that there are major differences in men and women. But this one never made sense to me, maybe because it's something I'm good at. You too it seems. All the women in my family can read maps, but then, so can the men. This has never been an area where I see a gender difference. Sounds like for a "chick," you know plenty! But shssh! Men apparently don't want to realize that! LOL!!
It's a generality, like, generally speaking, men are taller than women, women have bigger breasts, men have more muscle mass.
I am a man and I am a talker - and listener.
