That Awkward Moment When...

Do I know you from somewhere.jpg

You see someone whom you briefly talked to online/over the phone in the grocery store (or some other public place).  He walks up to you and says, "Don't I know you from somewhere?"  One could certainly say, "Sure - we met on Plenty of Fish a couple of years ago.  We talked on the phone once and you never called again.  I took an inkblot test shortly thereafter and they said I was normal, so I don't know what your problem is." 

On second thought, that's probably not the best course of action.

I made a few broad statements to clue him in on who I was. No dice.  He gave me his card, and asked that I sent him a friend request on Facebook.  Now it's my turn to be the flake. #karma #yeahbaby #imnotcallinghim

How would you react if this happened to you?
