If you are ever happily browsing in a shop in my part of the world, and hear a sudden terrifying crash, the chances are that it's me. Yesterday I managed to demolish an entire stand of reading glasses in Superdrug.

I don't know what happened, one minute there they were and I just nudged them and wham! Down they fell, scattered all over the floor. It was so embarrassing.

Mr Penry didn't know where to look, so he just took off and left me there, surrounded by all these unseeing spectacles. I found him later near the toothpaste section, laughing like a drain.

But I've always been like that. In the past I've accidentally demolished doors, cupboards, gates, letter boxes and even managed to disconnect the cold water tap in a public convenience in Brecon.... Sorry.
