The Seat Monopolizer
The Seat Monopolizer (carpe cathedra) can be recognized by their refusal to acknowledge the existence of other travelers, and bag placement on as many seats as they can reach. They typically inhabit standing room only buses during peak hours. Do not touch their bags as they are defensively territorial and may perform a threat display with bared teeth and low hiss which precedes a loud whining which is their main form of defense. It appears to be the goal of the Seat Monopolizer to take over the entire bus, and they are limited from this goal only by the number of bags a human can carry. Be particularly cautious around Seat Monopolizers who consider even looking at their bags to be a type of infringement on their personal space.
