A small prelude:
My wife and child went to the warm countries, I could not go.

A friend came to visit me today, and I smoothed a shirt for work. Here our secular conversation was interrupted by her phrase: "And why do you have a thermostat at zero?", and then she put it on "two".
It turns out that I have been smoothing things with a cold stove for more than two weeks :-/
It only lasted for half an hour.)
