Classifying bananas

Yesterday at dinner, in addition to other choices, Bow had three bananas to choose from. One was very fresh and had completely yellow skin. The other two were a bit over ripe, with brownish mottled discolorations.

When Bow decided that he was done with apples and was ready to start choosing bananas, he told me: "Give me the good banana." Since it was obvious he meant the one that was not overripe, I went ahead and gave it to him. When he was done, he spelled: "Give me the good bad banana."

"What does he mean by that?" Sword asked.

I looked at the remaining two bananas. One was somewhat less ripe than the other. "I think he means this one," I told Sword. "It doesn't have as many brown spots."

When he was done with the second banana, Bow told me he wanted the "bad bad banana." Since there was only one banana left, nobody asked which one he meant.
