You were walking down the hallway to your dormitory when you saw a stray cat that had apparently wandered all the way here. You crouched down and petted it, imitating the cat's meow, smiling.

"Meow.. Meoww~"

Ghost happened to be on his way back to his office, so he saw you meowing at the cat as if you were talking to it. He was also curious, so he crouched down next to you without you knowing, and suddenly he meowed in your ear with his deep tone and heavy voice, making you jump in surprise.
