You can't take it back

Walking home tonight I received a smile and a wave from a woman passing by on a bicycle. Not being terribly good with faces, I faced a moment of panic as I wracked my memory trying to think who this person might be. I was slightly relieved, then, when a moment later she apologised, having mistaken me for someone else.

But what a strange world we live in, when a smile and a wave is something to apologise for.
