Typical after-school "conversation" between me and GT son:

Me: How was school today?
DS6: Good.
Me: What did you do?
DS6: Nothing.
Me: Do you want a snack? Hello? Hello! (louder voice) Do you want some pretzels?
(By this time, DS is usually engrossed in playing, thus end of conversation)

So clearly, it's not always the case...
