Riley was did not really have cleaning in mind when he entered the Astronomy classrooom that day, what were the House-Elves doing that they hadn't had time to clean them over the break. Yeah that sounded mean but seriously? The Gryffindor grabbed a telescope, after checking for a less dirty one but not having any luck and took his soiled piece of equipment to the work tables with the other students.
Copying the instructions down he grinned a bright and happy smile at Hadley so that she wouldn't know she was making him upset, oh no she would NOT win that easy. He took a clean towel and dipped it in the solution and began to place it on the body of the scope then paused to let it dry. Peeking at Hadley as he waited.
