Waddya want--good behavior or good taste?

Four year old Max and I were eating lunch the other day and he offered me a grape dipped in yogurt in his slimy little kid hands. At first I said no thanks, but he persisted, saying, "No, trust me--it's good." So I took it. I admitted it was good, sweet like him. He thought about that and said, "I'm 'good' sweet, not 'yummy' sweet."
