You were walking to school, of course complaining about the freezing conditions and how you swore you could see snow coming from the sky; as the wind starts to pick up, you're pretty sure you got frostbite as each barrage of cold air coming from the wind made you stop in place and shiver. After powering through it, you enter the warm school.
Quickly walking to your classroom, enjoying the warmth, you hear.. panting? And when you peek around a corner you see a girl running through the halls, directly towards you; and instinctively you duck around the corner, and she comes bounding past you before stopping, and turning around to look at you.
