This, of course, is owing to his refusal to consider the fact that other people's feelings really matter or entertain the notion that he is a mean-spirited, loutish, narcissistic jackass instead of the wonderful guy that he thinks he is. My guess is that Carrie Patterson is a lot like some of the more strident of the Get-A-Life battalion. What I've noticed is that his cutting remarks just wash over them as if they don't want to see how very repellent and churlish John really is. It makes a lot of sense that his mother just sat on her fat behind and just let the geyser of carbolic acid she calls a son spew his venom over everyone who couldn't fight back because boys will be boys.
I can say this in smug complacency of my own because he looks to me like the absurdity called a mama's boy. I can well imagine his every stupid move gushed over by a cooing mother as if he were the first boy to, as Lynn would so delicately phrase it, pop out of a gal's chute. This would explain his agitating habit of not thinking about things because it would appear that he was told not to. It would also explain why he thinks of Elly as a maid. Until he left home, women had been isolating him from the world his whole life so he needed to return to normality.
