We speak English at home, and dh is "dad".
My dad wants to be called "ATI" which means "dad" where he is from. It's what I call him so its kind of weird to me. He should be "Star ATI" which literally translates to "old dad". He doesn't want to be "old".
My dh doesn't really care because it sounds nothing like dad but it still means the same thing. What would you do?
