Here is a conversation I had with Pumpkin on the way home yesterday:
Me: Wow, we're making good time. We'll be home to Daddy and Petunia in no time!
Pumpkin: Because there are only a couple of other cars.
Me (confused): What?
Pumpkin: You can go fast because there are only a couple of other cars. Just a couple.
Pumpkin: When there are lots and lots of cars, you go slow.
Me: You're right.
Pumpkin: And that's nasty traffic.
I can't argue with her logic. And yes, I do frequently comment on the nasty traffic on our ride home.
