"you" better be "careful"

thanks to reader Joy who sent this one to me today. I usually try to avoid more than one post in a day, but this was too good and I was too impatient.

Joy adds these two things:
1. The sign is not for "me" or my "dog." Although I do have one.
2. My favorite part of the sign actually has nothing to do with the quotes but the clarification (which, it seems, is neccesary) that reads in tiny writing "yes. you."

I didn't see that second thing without Joy's help, and now I love it more. Killer.
