Second on Selwyn's hit list was the Black Lake, and as he walked down to the lakeshore, he became aware of a teeny, tiny problem. While the Care of Magical Creatures paddock had had a lovely new fence all ready to have things stuck to it, the lake had nothing of the sort.
There was not even a low wall or bench for people to sit on and admire the water. How inconvenient. It meant not only did Selwyn have nothing to stick anything to, he also had nothing to sit on while he pondered his predicament.
The seventh year placed one hand on his hip and brought the other up to stroke his chin as he thought. Of course, he could just levitate his poster and leave it flapping in the wind, but there was something so tame about that. It didn't strike the right note of rebellion and insolence that Selwyn liked to think he was famous, or at least infamous for.
On the other hand, there were plenty of trees about. Even here, away from the Forbidden Forest where they were sparse along the edge of the lake, there were enough to draw the eye. It wasn't as good as defacing school property but they would just have to do.
Selwyn got to work with his posters, running from one tree to the next as he charmed them into place.
