Answer 2

A snowy night closed upon the world, and in
the morning one could scarcely recognize a
feature of the landscape. But during the night
the fury of the wind increased to such a
degree that it thrilled us with a vague terror.
As I lay in my bed that night, I wept as I
hope few children have wept.
