The phone rang this evening at the library information desk. The lady calling had a rather odd request. Her daughter was coming to the library to meet a friend for a study session. Daughter had borrowed Mum's car (yes, she was of driving age) and Mum needed to pass a message to her girl. Nothing earth-shattering, just a message about an item left in the vehicle. I was given a name and description of both the woman's daughter and the friend said daughter was meeting, with a request to please track the girl down and relay the message.
Sure enough, I found the two girls tucked in a corner, studying. Approaching the one who matched the woman's description of her daughter, I said "Excuse me, Sally*?"
Sally looked up at me with a mixture of confusion, fear and horror. "Um, yes?" I could imagine the thoughts thundering through her head in quick succession: Who is this stranger and how does she know my name? She looks like she works here, am I in trouble for something? Oh, no, has something terrible happened to someone I know?
I quickly placated her by saying "It's nothing bad! I just have a message from your mum." I gave her the message and watched the tension drain away, leaving just the confusion.
"Uh, OK, thanks," responded Sally, "but how did you know how to find me?"
I laughed as I walked away, saying "Sally, we mothers know EVERYTHING!"
*: Not her real name, for obvious reasons.
