My mom always said to always go dutch on dates. She said if you pay your own way, there will be no misunderstandings about who is indebted to whom.
I like this advice. This is good advice. The whole idea of the guy always paying creates an imbalance, with the guy always feeling like he's owed something, and the women always feeling like she owes.
We should do away with this custom, which dates back to a time when women didn't work, or didn't get paid well enough to be able to take care of themselves.
Folks tend to think that when feminists complain about the patriarchy, we're accusing all men of oppressing all women. But this is one of many cases where following the rules of the patriarchy is equally unfair to women and men.
