I had accidentally left my research books on the coffee table (I try not to do that, because it scares the normals) and they glanced through the stack when I went to grab some snacks.
"Uh, hon? *terrified glances at each other* Roman necromancy? Ancient Greek love magic? Is...is there something you're not telling us...? Should we be afraid?"
"No, I'm just working on a paper."
"Uh-huh. Then would you mind telling us why in HELL there's a copy of Harry Potter and a WAND in that pile??"
"...it's not a wand, it's a chopstick. I was looking for that!"
