Polite Company
I generally have buddies who are cool with talking about dead rats and poop and who'd excuse my need to spit out food in order to speak, but every now and then one finds themselves among the company of near strangers or people who may not share their interests or life experiences and then you have to be on your Best Behavior so they don't think you were raised in a barn, and still live there, and are in fact not even a human, you are just a farm animal that convinced itself it was.
I should really get that rat out of the yard pretty soon tho
