Snack Parent

I was "snack parent" at "W"s pre-school on Friday. These young minds amaze me. "W" is just starting to say a lot of sentences. He even has conversations with himself in the car on the way to school. They go something like this.
W1:water? (meaning may I have some water?)
W2:NO! (very abruptly, in a deep voice)
W1:plleease? (very politely and sweet)
W2:NO! (again, very loud and abrupt)
This is a common conversation that he carries out, asking for various things. I swear I am not that stern or bossy.
