The three-way stops along the main road out of the neighborhood are STOP signs, not slow-down-a-bit-and-see-if-there-is-car-coming signs! Even though it is a three-way stop, it is always good to be aware of the the fourth direction and, especially, the crosswalk. Please get off the phone, put out your cigarette and be aware of what is around you! Had my kids been with me when I had to stop short in the crosswalk, I would have chased you down.
