A conversation:
OWS: What did we do wrong in past lives to deserve this? Was I in the Khmer Rouge? What else warrants this kind of punishment?
Me: Not much else. Maybe genocide.
OWS: Khmer Rouge was genocide.
Me: Oh.
...
Me: You know not to use obscure historical references around me!
OWS: Sorry. [insert Wikipedia link for Khmer Rouge here]
