"Dad, did you just call me on your old cell phone?"
"No, sweetheart. I did not call. The phone is turned off and nobody can call it."
"But Dad, it rang twice. There was a message that said, 'Pick up, Amanda'. I thought you were trying to call me."
"Amanda, the phone was turned off when I got my new cell phone. Nobody can call."
"Dad! There were two messages that said, 'Pick up, Amanda.' One was from yesterday and one was from today."
"Amanda, I use the checkbook on that phone and it automatically updates my calendar. Maybe you were seeing some kind of calendar reminder."
"No, Dad! It was a message that said, 'Pick up, Amanda'" (Amanda was pretty freaked out by the personal nature of the message to her, and the more I told her it was not me, the more worried she became).
Finally, the light dawned on me. "Oh, Amanda. Sweetheart, I put "Pick Up Amanda" on my calendar for yesterday and today because Mommy was out of town and I was picking you up from school. Those were calendar reminders that I had set up for the "Pick Up Amanda" events on my calendar!"
