Harry flew until his hands were too numb to grip the broom handle, and then he flew a little bit longer. He landed in an empty courtyard on the far side of the castle from the quidditch pitch and staggered inside, frantically casting warming charms through chattering teeth. This section of the castle was deserted, to Harry’s relief. He couldn’t stand the thought of seeing another person right now. He leaned his broom against a wall and sunk down into a dusty corner, wrapping his arms around his knees, attempting to comfort himself as much as to warm himself.
