If I had my way, I would sleep about 12 hours on Friday night to catch up on the lost sleep of the week and prepare for the weekend. I often get my way. This is not entirely reasonable behaviour, but while there's nobody preventing me from doing it, I'll probably find myself doing it.
This morning I have a training course in London, which is why I found myself boarding a train at 8.10. This is totally unlike me and I feel exhausted. The train is on time and wasn't packed. This is unusual for trains. It's all weird.
