What do you mean what you wore or did at the grocery store?
I do get asked all the time. Even when I went to my son's class last week the kids wanted to know what I did at work-lol!!
I really don't find it odd and I never thought it was rude because you could "figure out" how much someone would make. You can't really know just by telling someone what you do how much you make.
Those are common questions around here too.
i have a sister who stays home, her husband has had the same, modest job for as long as they've been married.
honestly, the questions are great learning opportunities as well.
i find the money factor/how much you make question rude.
