I asked him, " What do you mean? Why do you think so?"
He answered "For example, look! This thermos! It's English!"
My old thermos is written "Thermos" in English, so I thought he was saying about that.
But he said, "This looks like the the form of the letter "I", doesn't it?".
He was not telling about the words of "thermos" written on it, but about the form of it.
I was impressed by the children's abundant imagination.
