{Reasoning}

Oh boy, he's only 3 and we are hearing this now. The kids got their bath in early last night so Ed told William that he can watch TV for 30 mins. Well, the conversation got interesting.

Ed: William, you can watch an episode then it's time to go to bed
William: I don't a TV in my room
Ed: You don't need a TV
William: But you have a TV in your room

I looked at Ed and said, wow, he got you there! :)
