A Grocery Trip or a Parade?

I took Connor grocery shopping with me tonight. After he ate his banana (which is his favorite thing to do as soon as we get into the grocery store), he was in an great mood. I was pushing the cart around, picking up our stuff, and he was waving to everyone he saw, shouting out "Hi, Hi, Hi." He got quite a few people to respond...and I felt like he was practicing for a parade.
