After the headmistress had given her speech, Penelope went up to the staff table. There were a few professors who she wanted to see, starting with professor Flamsteed.

"Hello, Professor Flamsteed," she said, smiling at the professor. Despite her bad experiences in every astronomy lesson she had ever attended, she actually liked astronomy class. Except for that activity in the first class. That had freaked her out. To this day she was still regretting not just getting out of the bubble when the professor asked her if she wanted to opt out of the activity. Nothing was worse than being in a bubble and a pendulum trying to hit her. Not even getting hit by the whomping willow had been as bad as that. Now was not the time to be thinking about the bad things. She was supposed to be thinking about what she liked about astronomy, not the part of the class that haunted her worst nightmares. Turning her thoughts away from the bad experiences, Penelope focused on all of the things that she liked about the class.

When she saw what Professor Flamsteed was wearing, all she could think was, "Running out of clean suits, Professor?" It looked like Flamsteed always wore a suit of some kind. How many suits did he have? If she always wore a suit but was out of clean suits, she would wear a dirty suit before she would wear what the Professor was wearing now. Surely there were cleaning charms that the professor could use to clean his suits.
