Will the Real MJC Please Stand Up

Here's a conversation I had with a boy in my Sprout 2 class yesterday:

A: "Teacher, you know my teacher."

M: "Your teacher at school?"

A: "Yes, her name is Holly and she says she knows you."

M: "She knows me? I don't think I know a Holly here."

A: "But she said she knows Michelle."

(Meanwhile, the other kids in the class explain to him that there is more than one Michelle in the world.)

A: "There's more than one Michelle in the world?"

M: "Yes, there are many people with the name Michelle, just like there are lots of Alexs, Kaitlyns and Julies."

A: "Ohhh... then it was probably a different Michelle."
