Have you ever been embarrassed by misunderstanding something somebody said?
It happened to me a few days ago.
I was on a public bus. I was bored, so I was playing Tetris on my cell phone. An elderly woman was sitting across from me, and I heard her ask, "Do you have a life?"
I guessed she was making a snide remark about my not having anything better to do on the bus than to play a silly little game on an electronic device, but I didn't dare use a snide response. So I just said, "Yes, I do."
Then she responded, "Where is it?"
