I'm not a man who tells women to smile, but it feels like a lot men were not properly socialized to treat girls and women like real people, like equals with their own complex worlds and emotions. Maybe it's also because a lot of men feel so removed from their own emotions that they will project that onto women, thinking nothing of asking someone put up pretense for the their sake. IDK. It's misogyny, it's entitlement, but men aren't born like that. They are socialized like that.
