Me: I'm going to school.
Sophia: Why?
Me: To work.
Sophia: Why?
Me: To make some money
Sophia: Why?...
Me: Ok, I know where you're going with this. You tell me why.
Sophia: I don't know why. You tell me why.
Me: Why?
Sophia: Because I don't know why.
Me: Why?
Sophia: Because I don't know why!
(Repeat this exchange several times with much laughter.)
Me: Is Daddy saying why too much?
Sophia: Yes.
Me: Do you want me to stop saying why too much?
Sophia: Yes.
Me: Good, I won't say why too much.
Sopha: Why? Haha!
(Sigh. The why stage has begun.)
