Was it a question or a ploy?

While the younger one was busy gulping down mangos, the older one had weightier things on his mind -

“Why is a mango not called orange when it is orange in colour?”

To say I did not have an answer would be a bit of an understatement. “Because it is called a mango”, was the best I could come up with.

By the time he realised his question wasn’t going to get an answer, the younger one had polished off both their mangos.

Wonder if it was just a ploy to get out of eating a fruit he doesn’t like?
