Sleep in.

You drift back into sleep, warm under your blankets, unaware of anything until something cold and wet hits you in the face. You sit up quickly, ignoring the cold wind biting at your skin. Someone had opened the window, letting in the cold air, and had thrown a snowball at you. You run there, and lean out. Overnight, it had snowed. The grounds are white and clean, and although the skies have cleared, and the weak winter sun is shining, no one is outside.

Suddenly, another snowball hits you on your head. You spin around to see Peeves shooting away, cackling, another snowball in his hand. You duck as he throws it, and the snowball misses you by a few centimetres. Peeves sticks his tongue out at you, then shoots out of sight behind a tower. You close the window, and get dressed in your warmest clothes. Although you have a lot of work you could be doing, the snowy grounds are calling you.
