It was on a Trip home from this pub I stumbled upon last November in the Fall.... It was more this Totty tottering that tipped me to take a tumble .... :(
a few weeks back walking on a brick pathway Lilac flowers all over the walkway stepped on some and it was just like a banana peel, fell forward broke my fall ok but tore up shoulder a bit, but all healed now.
On ice at the landing of my outside steps this past winter. I slipped and fell. Went "Whoa!" under my breath -- I stood up -- and slipped again, exactly the same way. I looked just like the guy in your question, I bet! Ha!
That's happened to me before -- or, in the dark, I think there is one more step but there isn't. And I get all fumbled up walking as if a step would be there. :)
