Probably a lot of guys are the same way so don't want to pick on one side (edit - couldn't use the word I had there!) or the other - people in general are that way.
But I agree with your comment as far as it goes.
I found a good one, I don't think I've spent 'any' on her over what she's spent on me, she doesn't like small shiny things and shops Runnings or other Fleet & Farm stores for most of her clothes, enjoys stuff I enjoy.
Hope I treat her 1/2 as good as she treats me.
