“And have you noticed, Smurov, that in the middle of winter, when there are fifteen or even eighteen degrees of frost, it doesn’t seem as cold as it does now, for example, in the beginning of winter, if there’s suddenly an unexpected cold snap, like now, of twelve degrees, especially when there isn’t much snow. It means people aren’t used to it yet. Everything is habit with people, everything, even state and political relations. Habit is the chief motive force.”
