Today Isaac spotted this sign while we were out running errands. He asked me what it meant. I decided that rather than tell him right away, we could have a little lesson.
I asked him if he knew what the "circle-slash" meant. He did.
I asked him if he knew what the letter in the middle was. He did.
Then I asked him to guess what the sign might mean, based on the two things he knew about it.
Isaac's voice got real quiet and he said, "I think it means no going to the bathroom on the street."
Well, I guess that's one way to read it.
