How annoyed or angry should one be at people who are socially incapable?

Speaking as someone who used to be completely socially moronic, I know it is possible to change. It’s a state that can be improved but it does take effort and time.

Once I figured out that it was a system with rules that could be learned (and hacked), it became much easier. I’ll always be an introvert but I can make people think I am perfectly normal for a few hours, and sometimes even seem or be charming and witty.

It takes a toll, though. It’s not my natural state. It’s as tiring as running 10 miles.

What of the people though who just give up and are socially dim-witted their whole lives? How should we treat them or think of them?

I think I tend to be harder on them than needed because I changed, because I bettered myself, and I assume they should be able to as well.

Perhaps this assumption is wrong or unfair but hard to keep from thinking this way.
