NPC Behavior #86 

NPC Behavior #86 is a behavior done by an individual when they only do something just because other people are doing it, wether it would be hating something or loving something, they would follow along without a second thought.

This behavior is common amongst people who likes to fit in with a particular group or person. They wouldn't hate if no one hates, they wouldn't love if no one loves. They are generally just NPCs at this point
