I decided to phone my unknown caller today, and I reached her answering machine.

"Good morning Ms. Donaldson," I said. "This is Katie, the woman you mistakenly call every so often. I just wanted tell you that I love getting your messages and they always brighten my day. And thank you for your Mother's Day wish, yes, I am a mother. And if you're a mother, I hope you have a great day, and if you're not a mother I hope you have a great day. I look forward to the next time you get your numbers mixed up."
