    It was about seven years ago. I just picked up my three­year­old daughter from the nursery. I was weighed down with shopping bags, and with my daughter’s things. We arrived at a pedestrian crossing and she pressed the button. In the distance, I heard alarms, told my daughter to wait and watched a police car approaching.

Little did I know, as the_green_man flashed, that my daughter had begun to run into the road. I watched the police car speed toward us—that’s when you sounded your horn and waved wildly to me. My daughter was about a meter from the path of the police car, hidden from their view by your car.

I screamed her name and ran toward her. She stopped and was shocked by the rush of the police car as it sped past. She wondered why you had blown your horn, asking, “Mom, why was that woman so rude？” not realizing you had saved her life.

She wondered why I picked her up and burst into tears. My legs gave way as I reached the other side of the road. I should have followed my “wait” with a hand on her shoulder, or an explanation of why we were ignoring the green man this time, especially as I had in effect conditioned her to cross the road at the sight of the green flash.

I beat myself up for months, and still do, with flashbacks and horrible assumptions about what might have been. But for your sounding your horn, seeing what I hadn’t seen, I would have been left a mother on the other side of the road, totally broken. I apologize for putting you in that position—I can imagine that it upset you, too. You saved her life and I am so grateful.
