Betty couldn't help but laugh as one of her students walked into her shitty little office. She didn't recognize any of them yet, as nearly all of her encounters had been over journals, so far. Still, she had no problem with them dropping in unexpectedly. If she really had wanted to have some privacy, she simply would have locked the door.
"Have a seat! Do you want some wine? I mean, I have half a bottle to go, but I'm not beyond sharing." Lifting her wand, Betty quickly transfigured a random piece of paper into a wine glass similar to her own. Nifty trick. Hell, she might as well show off, since she'd have to teach this shit next year.
"Now, who are you? Have we chatted yet? I'm assuming you aren't Draco Malfoy."
