Just another spelling test

Yesterday, I was giving a spelling test to Matthew and Andrew.   The word was "healthiest".

So I said, "Who is the healthiest person in our family?"

While Andrew was writing the word, he said, "I think Joseph is the healthiest person in our family."

To which I responded, "He drinks pop for breakfast, I don't think that's very healthy."

Then Therese piped in and replied,  "Well, at least he doesn't skip breakfast!"

Hmm, maybe we should define "healthy", first.
