I had pegged my number of "falling down on some wintry surface" incidents at one per winter season. I fell once last winter on a slippery sidewalk. It hurt. A couple of weeks ago I fell again on an icy sidewalk that was covered with a dusting of snow, thus obscuring the ice underneath. The puppy was with me on her evening walk at the time and though she wasn't really to blame, she certainly didn't help the situation. Luckily since she was along I was able to foist blame upon her for the fall.
For some reason I thought it to be an intractable truth that I would only fall once a winter, and I'd already gotten mine out of the way. I discovered this morning that this was not true.
