My wife best friend is married to a “functioning” savant. I would say he less Rainman but more asshole.

Dude can’t catch a hint to save his life. Social cues are totally out the window. Dude just doesn’t know the right thing to say at any situations.

I have years being upset with him and even having verbal battles with him.

I realized that I was in the wrong. He simply lacks the ability to comprehend why he can or can’t say. Why am I wasting my time getting mad at him.

So I guess in this scenario, his brain has too many wrinkles that it’s sorta smooth again.
