We only have a week left to prepare for our O.W.L.S and I can’t deal with a huge hangover right now. It takes a few minutes for the potions to start working. We spend our week bowing over our books and asking a lot of questions in class, to fill in missing information we haven’t figured out. The potions help us stay focused for a longer time, but we only drink them when nobody is watching us. The worst thing that could happen if people started spreading rumors that we are addicted to a potion, we don’t need that kind of attention.
