Third time's the charm

So, then came dinner and I heard that familiar sound ... a cup crashing to the floor. I haven't seen any of these crashes while they were occurring, so I don't know for sure how they are happening. I think this one was the result of a misplaced elbow. At least this cup was mostly empty. There was some ice, which he proceeded to eat instead of pick up. But he started the clean up without any prompting this time. That sounds like progress, huh.
