Possibly, but doesn’t have to be. I grew up in a home that was built as a duplex, one apartment per floor. So the stairs were 17 unpadded wooden steps that were straight down - no landing or turn. I slipped and fell down them when I was 4. I clearly recall this. But that made me remember that I had done the same thing a year or even two before (which was worse, because at age 4 I was large enough to stop myself before I hit the bottom - not so much at 2-3). I wouldn’t remember the first incident without the second, but because of it, I do. The stairs got carpeting shortly after that.
