Derry walked down to the Greenhouse, wearing the boots that she used to wear to muck out the horses and feed the chickens... her dad had wanted her to get new school shoes but since these were black, and she could clean them easily, she hadn't let him spend money on new ones - and it seemed to have paid off, couldn't go around wearing flimsy little shoes when they were doing plant stuff, could she? No.

When she reached the greenhouse she spotted the Professor and, with only the tiniest bit of a stutter, greeted her. "Good D-day, Professor." she said with a small smile, taking a seat on one of the stools and looking around.

Derry liked plants, flowers especially. She wondered if any of them could actually sing, like in Alice in Wonderland... even though they didn't have larynxes (which, according to her mother, made the whole thing impossible... but her mother said a lot of magic was impossible... that's what came from being a half-blood, apparently.)
