We forgot to tell Piper "Excuse Me" can be used in many contexts!

Piper and I were in Target on Monday night and were done shopping and heading out to the car. She was in the cart I was pushing and just as we started to walk outside I stopped suddenly, as one of the Target employees was coming with a long train of carts bringing them back inside the store. He startled me, so my reaction was to stop our cart, back up slightly and say, "Excuse me". Apparently we startled him too, his reaction was the same and after he stopped he motioned us to go ahead. So I started pushing the cart again, heading for the car, and as we walked off Piper looked at me and asked, "Mommy, toot?" I laughed all the way to the car!
