S-T-O-P means "stop"

... said Zoltan to me this morning in the car. This is a child who only recognizes half the letters of the alphabet, can't draw a letter that looks like anything other than a scribble, and still colors like a 2 year old (i.e., all scribbles). Yet, at not-yet-four he recognizes the stop sign. This is not a child following in his sister's path!
