explaining cars to the old lady

i don't think the women in our lives get enough credit weather they are interested or not, they put up with it, but it makes it alot more enjoyable for me knowing if i need to buy something for the car that I have her blessing. It's also nice to talk about something I know a little bit about, and actually have her listen to me, unlike the wedding plans she keeps making while i watch tv and say uh huh sounds good babe, whatever you want, haha, is that bad?
