I driving with my kids to the bank, when one of my children asked, "Where are we going?"
Me: The bank
Kid: What are we going to do there?
Me: I need deposit a check so we can have money.
Me: So we can buy the things we need.
Kid: Oh, so then why are we here?
Me: So we can go to the bank.
Kid: Why do we need to go to the bank?
Me: So that I can take the money from this check and put it in a safe place.
(By this time, I was past annoyed by the onslaught of repetative questions.)
Kid: Why do we need to deposit the check?
Me: I already answered that.
Kid: What are we going to do with the money when we get it?
Me: Why are you suddenly asking so many questions?
Kid: Sid the Science Kid says we should always ask questions!
Of course he would. Of course he would.
