Gosh I thought I was tired yesterday but now I'm really tired. I had to get up at 5:30 to come into work for a maintenance slot. The colleague who insisted we do it so early turned up 45 minutes late! Still at least I can leave at 3 this afternoon. I'll go home, fiddle with Napoleonic Wars for a couple of hours (I'm trying to absorb the new rules) then get a very early night I think.
