The grandmother that said housecoat and house slippers grew up on Long Island. I don't know if that makes those words regional?
Momo said 'Listen' also. It's funny, but I'd never heard that usage other than by my other grandmother. She was born in Texas, so maybe regional, once again?
I do know that soda vs. pop is regional. I've even heard a hybrid...soda pop!
Very interesting, and interesting that we have the same usages more than not!
