I knew it was warm, because the kitchen wasn't cold, so when I decided to go out for a snack, I didn't go to the trouble of lacing up my winter boots, and just slipped on some boat shoes (OK, I'm a WASP Even if I don't have a boat, I ought to). Outside, it was just above freezing, rainy over ice, and incredibly slippery. And the shoes I'd chosen didn't give me any traction at all.
So, I walked very carefully to the nearer of the two snack options, the other one being down a slippery hill. Because I didn't want to fall.
Now, that's sensible reasoning at any age. But I find myself reasoning like that at this age. I'm not sure I like that very much.
