That thing...

You know that thing where you think about someone who's died, and you think they're still alive, but then you remember that they're dead?

And then you laugh to yourself because you know, duh! Thicko! And then someone asks you why you're laughing and you say, 'I just remembered Aunty Beryl's dead.'

That thing, my friend, that thing will get you into all kinds of trouble.
