Harry Potter turned the corner of the corridor, and breathed heavily

Exertion

Harry Potter turned the corner of the corridor, and breathed heavily. No, this certainly was not normal. Seventh years didn't do things like this. Hell, even fifth years didn't do things like this. It was a preposterous, brainless, and all around stupid thing to do. But yet…

  Harry peeked carefully around the corner, flicked messy black hair away from his forehead, and squinted. No one was there. Good.

  He stepped into the corridor, and started stealthily sprinting, fast and quietly, down to the one adjoining it. When he got there, he peeked around the corner again, and sighed with contentment. Again, no one was there. Very good.

  He must be way ahead now. Fantastic.

  Harry stopped in his tracks, and stepped into an abandoned classroom. He sat on a desk, and wiped his sweaty forehead. He then took off his glasses and cleaned them on his robes.

  'Why am I doing this?' He fiercely asked himself, once he was breathing properly again. The running had put him on edge; it made him feel all hot and bothered. He swung his feet underneath the desk, and sighed. He then jumped off it, and, after looking through the glass panes of the door, tiptoed into the corridor.

  He didn't bother to peek around the corner of the two joining corridors this time. That was his big mistake.

  "Tag!" Ron Weasley cried joyfully, smacking Harry around the shoulder and then skipping around the corridor. "You're it!" He then sped off in a different direction.

  "Bloody hell…" Harry muttered. "I am so bad at this game."
