S-T-Zero-P

On today's walk, we learned that the letters on the stop signs spell stop. Each time we approached a stop sign, the following conversation ensued.

P: S-T-Zero-P that spells stop mom!
M: It's an O, not a zero.
P: Ok ok, S-T-O-P. Stop.

When we got home, he wanted to write the word stop with his sidewalk chalk. I was so proud of him, I had to take a picture. It's pretty crappy because it's a cell phone picture, but you can sort of see it.
