I woke up at 5 this morning, to the groggy realisation that I'd fallen asleep with the light on, my computer on, my mouth guard not in. I flailed around, worrying I hadn't brought my phone up and so had no alarm. The idea of getting out of bed in the cold and dark to go find it seemed impossible.

Then the knowledge that it was Saturday dropped me back onto the pillow with almost fainting relief. Not only did I not have to go get the phone, I didn't have to get up for work either. It was a glorious, dizzy sensation. If I hadn't been lying down, I might have fallen over with it.
