The guy kept repeating, “You don’t know who this is?”
“No, I don’t know who it is. Tell me.”
Then the guy starts yelling at me, “Grandma! You don’t even know your own grandson?!”
I said, “I’m sorry, I’m not your Grandma. You have the wrong number.”
He apologized. After we hung up I laughed. Then I really thought about what had happened and how sweet it was that someone, somewhere, was calling their grandmother. And how lucky they were to still have a grandmother. I was touched.
