The stairs were slippy, not because something had spilt on them but simply because that was the way they were - slippy. You had to be careful going down, or even up . . . or at least it was advisable that you be a bit careful, a bit aware of their slipperiness . . . though maybe that's going a bit too far, more than likely, aware or not, you'd be fine however you chose to come up or go down; but however there was yes the chance that if, lacking in all restraint, you were a bit flippant in the manner in which you attacked these stairs, then who knows what might happen . . . that is you might fall, and it might even be a bad fall, though of course on the other hand it mightn't be bad at all.
To be honest, I've forgotten why I brought up these stairs and their slipperiness. They must have been leading somewhere . . . but where and why though, if they were, I've no recollection. Though then again maybe they weren't ever leading anywhere, and that's all I had to say all along.
