Lying in bed last night I was exceptionally tired but finding it hard to sleep because of my wriggly body. My blind was open a little and the orange light from the lamp-post outside was creeping in through the gap.

Tired of shouting at the lamp-post I turned over and faced the wall. My arms were waving about, which meant that, with the light cast on the wall by the lamp-post, I was treated to an involuntary shadow dance. This made me laugh, and my frustration at not being able to sleep melted away.

While my motor tics kept my arms waving, my vocal tics gently called out:

“Lamp-post, I’m dancing with your light.”

It can’t have been long before I was fast asleep.
