I would say nothing, but then he just yells at me until I give an answer.Valid points never work on parents. Ever. 0% success rate for me. It's a bad idea. But I'm sorry about that, because the personality thing is something I can hardly understand.

Well in that situation, I would go "Whatever honest answer I would give you wouldn't be satisfactory." And with you dad, I'd get yelled at more. And I don't really know how to explain the personality thing, other than try to imagine your brain switching to a completely new person, changing who you are while you still call the shots on your actions. I should break that news to them sometime.
