For context my DM has always been this way so it’s not down to old age.
She always refers to people by their looks, so for example she was telling me of a girl she used to babysit and she described her as “a bit ugly” (she also made a comment of her dad being good looking).
i reminded her that I’m not a universal beauty by any stretch of the imagination and that I was bullied for being fugly, so it’s a touchy subject for me. As well as not being nice to call someone “ugly” just because as it’s a) completely subjective b) a negative thing to say.
