when people refer to their parents by their (the parents') first names when mentioning them in a story. I don't know why, but it really grates on me.
Steven: Hey Ben, who'd you have dinner with last night?
Ben: Oh, just Jerry and Sonia.
It just sort of smacks of...teen jocularity, and reminds me of a sort of personality type that I don't care for, the type of teenager who grows up to be the "cool teacher type" the kind who calls all the kids bro or dawg or something.
It does NOT bother me when someone uses the first name in this way
Example - Steven: How is Jerry?
Ben : Jerry is good.
that seems alright to me.
