How Rolling is Confusing

Ha ha. Here's an example that anyone can understand, using a single picture.

You know this one from yesterday?


Well, maybe that was kind of upside down.

When I took it, if I looked up, there was the floor.

If I looked down, there was the surface.

So...maybe this is right side up?

Hmmm.

Confusing?

Great! You got the point!
