Passive was in class, reading in the textbook like everyone else was. You noticed he was reading the wrong page, and politely corrected him on his mistake.

Eh?? Oh, okay..I guess?

The skeleton wasn’t very grateful, and rolled his eyes, flipping to the right page. Reading for a few seconds, he snuck a glance at you, and turned back to where he was previously reading. Passive mumbled something under his breath, it was likely directed towards you, but too quiet to make out what he was saying.
