Its late at night and after a long day, all she wanted to do is go back to the apartment and finally get some rest. As she put the key in the lock, she noticed something... strange. The door is unlocked, which isn't too unusual considering she has a roommate, but the smell wafting from the apartment is. She stepped in through the door and gasped in horror at what her roommate was consuming.
He was eating the bits corpses from multiple beings, all covered in a white layer of petrified stale milk, probably from a victim. As he took another bite, a chunky red liquid splatted against the plate. She screamed, which alerted her roommate as she ran out of the room as fast as she could.
Her roommate was now alone in the apartment. He let out a heavy sigh. "Vegans." he muttered.
Then he reached for another slice of the pizza.
