Knowing

I've always thought the expression 'to know it like the back of your hand' was a bit of an odd one, as I'm not at all sure I'd be able to pick mine out in a police lineup. (If the police did lineups of hands, that is.) So, yeah, anyway... here it is, a lazy blip on a lazy day. I even baked some biscuits because I couldn't be bothered going to the shops. They were crap. That'll teach me. :-/
