Confidence

I broke out into hysterical laughter when I looked through the papers my son brought home from school today and found this. It is part of a first grade math test. He scored a 100%, of course, but had to explain how he knew, or arrived at, an answer. His written reply,"it's just because i'm smart."
His teacher wrote in response,"yes,you are."

That's my son...fully confident in his own intelligence! Heaven, help us!
