I did that with my daughters. I had them actually change a tire so they'd have the experience ... just in case. Still, I would hope they wouldn't have to unless they simply wanted to.

Of course, being old fashioned, I still hold the door for my wife (most of the time) when she gets into the car. It just feels right to me to do that. I guess if she complained, I would stop, but would probably feel a bit uneasy about it. In fact, I generally hold the door open for ladies entering a store or offer my seat if I'm sitting in a waiting room and notice a lady standing because no chairs are available.

I guess I don't think about that being gender bias. What do you laides think?
