Benjy had been doodling, ahem, we mean, writing notes, on his parchment, and only now they were doing an activity zoned properly back in on the Professor. For the last few minutes, his mind had been considering whether one could spells like Arresto Momentum to make skateboarding tricks even more cool - or that was just a travesty, taking away some of the skill needed with magic.
