After a full day in the burrow, walking becomes difficult, but it's better this way. Spending time in the warmth helps a person endure the cold more. If you come out of this warmth, from an atmosphere of fifteen or twenty degrees, as is the case in the cavity near the warehouse, you will feel the cold and suffer from it, and it will take time to get used to it. The cold hurts, as if the air were just glass. You try to breathe, but nothing enters your lungs. But anyone who spends a full day in the cold knows that those who come from the warmth can move, walk, and climb a hill, when they can no longer endure it. Because someone who has been exposed to the cold for a long time wants to stay still, shivering, letting themselves get cold until everything stops hurting and they die.
