Late night

I was the last night librarian tonight, so had to stay until 7pm and be the 'responsible person' on duty. I did my best - fortunately, there wasn't anything much that I had to be all that responsible about, apart from putting the till money in the safe at the end of the shift. I *think* I followed all the instructions correctly...

I know 7pm doesn't sound very late, but it means I don't actually get home til 9pm, so later than I'd like. I'm just about to have a bowl of porridge, catch up on a bit of Casualty, and then be off to bed. This work malarkey is exhausting!
