Or, I think I've caught something
It was Scarborough that did it.
We had a lovely day, walking up and down the prom, eating candy floss in the car,* going up and down the cliff lift, avoiding the waves that were splashing up over the edge of the prom and over the road: the sea looked like an over-full bathtub. But it was the cold, biting wind, that left me feeling half-asleep and jammed up for the past couple of days, left me wishing I could stay tucked up in bed asleep for a week.
* so it didn’t blow away. The candy floss, not the car.
