Fourway?

Conversation in the back seat...
Brenden: Are we on the freeway?
Katelyn: No, that is the freeway over there.
Brenden: Then are we on the fourway?
Katelyn: What is the fourway? There is no fourway.
Brenden: I am free and I go on the freeway.
Katelyn (smart little cookie): Brenden, it is the freeway, not the threeway.
Brenden: That is what I said, the freeway.
Katelyn: It is the freeway. There is no fourway, or fiveway, or oneway, or twoway!
Brenden: Oh.

I just quietly giggled in the front seat! I love my kids!
