Human nature and annoyance

As far as I can see, human beings spend their lives rolling their eyes about how stupid they think other people are. Perhaps it would be more sensible to agree that, yes, people are goofy, flawed, and annoying, and stop being surprised or annoyed by what is the case? There is no reason for surprise at what has always been, or to give in to feelings of annoyance when the source of those feelings cannot be avoided, unless you are willing to become a hermit (which you probably aren’t). Yet, it seems to be human nature to be annoyed at other people’s human nature! Particularly when one is in a bad mood, of course.
