As I returned from a University for Seniors class this morning at UMD, walking on snow-packed and icy sidewalks, I thought of how parental advice can be problematic in these situations: "Stand up straight" and "Watch where you're walking!"
If you stand up straight, by looking farther ahead, you might not see a slippery spot at your feet.
If you watch where you're walking, you'll get a sore back and might walk into an overhanging tree branch or protruding shrubbery.
As I pondered these profound thoughts, I stepped off a curb at an alley, my boot skidded on some ice, and I went down on one knee and then to one forearm. I didn't damage anything, but I soaked a knee of my jeans and my gloves.
Nobody saw me that I know of. I picked myself up and continued the couple hundred feet to my house without any soreness.
I don't remember which advice I was following - "Stand up straight" or "watch where you're walking!" Whatever, one of them didn't serve me well.
