Several of Nate's kindergarten friends came to me upset that "someone" had sat on him - though there was disagreement over who exactly that was. I decided to check with Nate himself, who was apparently unfazed by the incident and was happily playing tag. When I stopped him to ask who sat on him, he called over his shoulder (as he ran off to continue his tag game): "I don't know. I couldn't see. Someone was sitting on me".
