Are You?

I've made it a habit to call for Bea whenever Henry and I come home from school, errands, etc.  I tell Henry that we are going to go find Bea, and we run around the house in search of the dog.  I say "Bea, where are you?", and Henry gets pretty excited when he spots her.  Henry has picked up on this game and now applies it to whatever object we are searching for.  I'll ask him to go find his shoes/sippy cup/Blue Bear, and Henry says "Are you!"  It is pretty cute...
