Is it possible for HutcH to raise a polite child?

So, the other day I asked Henry to do something for me. Lately getting him to actually do something when I ask is a chore. (Fate getting back at me?)

Anyway, when he did it I praised him and said "Thank You Henry". (Positive Reinforcement, right?)

His response was, "It was my pleasure!" (He must get that from his mom!)
