Serious(-ish) question now.
How is this man still able to function in public with all the insanity that goes on around him and the words that his own sisters (for one) scream out? Is the dude's skin thicker than a battleship's hull? Are the onlookers pitying the very clearly only sane man in a given conversation? Are the inhabitants just that inured to those shenanigans that anyone who reacts is clearly newbies to the area?
How has he and the girls he interacts with have not been socially executed yet?!
