Confusion

You'll be pleased (yes you will) to learn that I slept very much better last night. In fact when the alarm went off at 7 o'clock I felt well enough to get out of bed and head for the bathroom for my ablutions before donning the work-clothes I'd left ready on the radiator the night before.

Just before I left the room Boggy-on-the-radio said it was Thursday the 17th of March. That puzzled me. Why was I awake and getting ready to go to work? I don't go to work on Thursdays.

I went back to bed for half an hour.
