Wrong number?

That was odd. I had just gotten to my office this morning when my cell phone rang. I thought it was probably Mitsuko, and wondered what I had forgotten. So I thumbed the button, and raised it to my ear, saying, "Moshi, moshi." (which is the Japanese "Hello?")
( Don't call me, I'll call you . . . )

It's good to start your day with a puzzle, I guess.
