Wait, if am I reading you as saying that this individual contacted your daughter and said something like, "hey your grandma wants to talk to you and help you out and stuff because she cares". AND...this person was not a familiar individual to your daughter?
This is like adding an extra layer of triangulation to the mix. They don't realize, the meaning is completely lost when you have someone else send out your "heartfelt" information.
My FOO does that sometimes too. "Hey, your family wants to see you" or "so-and-so would like to call you or talk to you" and I think to myself, "ummm...they have a mouth - they have fingers - they know my phone number - they know my e-mail - they have access to my FB - they could contact me if they really wanted to". That's what I said to one of my siblings. I said, "they are welcome to tell me that themselves then - I believe it when I hear it directly from them" - guess what the response was??? SILENCE.
