"Mom, what's a ca-too-shon sign?" asked my 9-year-old.
"You know...ca-too-shon. I am drawing a building with a fence around it and fences around buildings always say, 'ca-too-shon.'"
"Caution? Do you mean a caution sign?"
"Oh! That does sound more right."
Ah, kids. Positively love the way their minds work!
