Wibby: Dammit, I can’t ever remember how to turn off this cell phone.

Margaret: On your phone it’s easier just to turn the ringer way down. See this little silver toggle on the side? Click the top of it to make the ringer louder and the bottom of it to make the ringer quieter.

Wibby: Oh, I can do that– that’s easy to remember!

Margaret: You said the same thing the last twelve times I taught you how to do it.

Wibby: Fortunately, I won’t remember that mean thing you just said to me, either.
