I don't. I don't assume anything. And neither should you.
My wife is my business partner, my daughter is a botany major. Both are quite a bit smarter than me in a multitude of ways. I don't have a son.
Nonetheless, I'm the one that maintains the cars, not by choice, but because the females *don't want to*.
My wife has always carried jumper cables, but has called me a couple of times to verify that she's hooked them up correctly.
My daughter has been instructed (after an unfortunate incident with her incompetent boyfriend) that she is to be responsible for tire changing, battery jumping and any other field-expedient repairs. She once brought the car home with a piece of broken plastic held away from the tire with a tampon string. I was impressed.
What does that have to do with anything? My wife and my daughter couldn't do it and wouldn't if they could. Ninty-five percent of the men I know couldn't do it.
Just because *you* have the skills to do such a task doesn't mean that others, men included, do.
Wow, making sure that a female has the tools and skills to handle a dead battery is a sexist comment? I thought I was empowering them...
Don't make assumptions about people and their viewpoints. I've hired females in non-traditional jobs and if anything, I've put forth an extra effort to encourage females to tackle non-traditional tasks.
