Analysis Solidified: Caino Hypocriens is an Antisocial Species

 It is easy to get along with someone who has genuine social skills. 

 It's difficult to create a misunderstanding and impossible to perpetuate one. They understand wording is difficult and correct it to what you meant as opposed to what you said. They employ radio protocol, discounting anything that's only been transmitted once. When they notice a discrepancy, they ask for clarification instead of trying to play one-up gotcha.

 They're likewise almost impossible to offend. If you tell them something true, why would they be offended? The shame is the fact. It doesn't become more true if it's said out loud. If you say something false, why would they be offended? You're only shaming yourself. You can't hurt the socially competent with words. At worst, they'll stop talking to you - if you consistently make it unprofitable, they will in the end stop fighting it and declare conversational bankruptcy (on your behalf).

 Grass monkeys aren't like this in the slightest. When you're talking to one, you have to go to enormous lengths to compensate for their atrocious lack of social skills. 

 They're offended by everything, so you have to walk on eggshells. They can't understand even minor polymorphisms, so you have to word everything precisely. They refuse to accept correction or admit to error, so you have to say it right the first time. They have no patience, so you have to say it quickly. They come up with elaborate etiquettes because a) they can't understand the difference between necessary and unnecessary and b) they can't handle anything composed on the fly. It has to be ritualized. Practiced ahead of time. Puddles are out of their depth. 

 The only skills dire apes practice are deliberately fostering misunderstandings. Deliberately trying to make conversation as hostile as possible. 

 Antisocial animal. Diagnose the whole species with oppositional defiant disorder, it's merely a question of who hides it better. Have to grade on a curve though. If a score of 120 is pleasant conversation, the children of Satan rate from 5-21.
 Grass monkeys are smelly and stinky because they want to be offensive. Don't worry, Gnon cheerfully grants this prayer.
