"Hi, can I speak to Charlene?"
"You have the wrong number."
"Well, can you take a message and give it to her?"
If you ask a person at a wrong number to take a message for the person you are trying to reach, d'ya think it will get to her?
(Just for the record, I was very polite and with only gentle laughter did I say, "Well, this is a wrong number. I don't know any Charlene." The woman, and it was a woman rather than a girl, said an abrupt thank you and hung up.)
People are so funny sometimes.
