I Hate When That Happens, #7452(b)

When you're in the pub, and someone you don't recognise or remember from anywhere, all of a sudden sidles up and starts talking to you. And they address you by name, so they clearly know who you are. But you haven't a clue who they are. So you let them keep talking, in the hope that something they say will give your memory a helpful jolt. But it just doesn't happen. And then, slowly, it starts to come back to you. You've met this person just once before. Once. And what's more, it was about four years ago. So you wonder, when you can't remember this person at all, what must you have done to make yourself so memorable to them? And just how much alcohol was involved? And are there photographs?
