He's so innocent

So Sam got in trouble for smacking other children with his hat on the school bus yesterday afternoon. Pretty normal kid stuff and while mildly annoyed I wasn't really angry but I gave him a talking to (and took away his favorite hat - I guess he still does have stuff to lose). I started off by saying that he was perfectly capable of behaving because he was a smart boy who knew right from wrong. He asked me why I said he was smart...

Made my heart tremble a little.
