"And when exactly was that?"

"Oh, about a week ago."

"I was here a week ago today, but I don't remember meeting you." I'm not sure what to say. I look harder, trying to make my eyes focus.

"I could have sworn it was you." I'm probably scaring him away with every word I speak.

"I don't think so, but my name is David anyway." I don't believe him, that he doesn't remember, but I decide to play along so not to scare him.

"Hi David, I'm David too."
