...think I found:

the alien which sucks out all the warmth. Out of my feet, out of my body, out of my head. And out of this town in general. It's lurking just around the corner in my neighbourhood. I wonder if anybody had a chance to flee.

Two and a half hours with a hot water bottle under my desk weren't enough to defreeze my feet. I could need some more for fingers, throath, back, chest...
This working day might end a bit sooner than usual as I think I can't work with a duvet wrapped around me and my feet in a bucket of hot water.
If I'll go for the duvet option be sure to find this photo replaced later.

Happy winter!
