Another puzzle

I don't want to come across as sexist, but there are some differences between men and women that puzzle me. For example, why do men name things with combinations of numbers and letters but women name things by description or designer? What is it about driving down the road that makes so many guys act like it is a contest to see who gets there first? I still catch my husband, a reformed speedaholic, gritting his teeth and clenching the steering wheel when cars pass him on the highway. Why is it when you talk to most guys about something, they think it is some kind of test to see if they can come up with the right answer, even if you didn't ask a question? I don't mind that we are different - it is a puzzle though.
