Oooh, I certainly wouldn't want to trip and fall while skating around, no. It hurts something awful, particularly if you're going too fast.

Then it seems I'll be coming up the steps after all. If you're there and I just can't see you, I certainly want to know about it.

I borrowed it from an old story, I'm afraid, but it goes like this: "What walks on four legs in the morning, two at midday, and three in the evening?"
