It was just your average day in Potions class. Nothing to do but sit there and pretend to listen to Snapes lecturing. Nothing new there. Zach was spaced out, dreaming of playing Keeper for the Ravenclaw Quidditch team. That would be great, he thought. Maybe then I'll make some friends...
Zach was an extremely shy 2nd year. He was smart, creative, and imaginative. The only thing keeping him from being a well-known student among the halls was a few friends, which he could never seem to get.
(Your character is sitting next to me in Potions, take it from here! :3)
