I took Daniel with me to run an errand tonight. Just him and me. As we were walking in the store, a family I semi-recognized was walking in. I said hi. The dad looks and me and smiles, then does a double take and looks at Daniel. He looks up at me, smiling, and says: "He's black."
That's all he said. I just said, "Yep, he's black."
The (black) cashier heard all this and was dying laughing.
I've heard lots of funny comments and/or looks, but this one wins.
