You’ll find that one in the book of Proverbs.
Don’t be friends with angry people. Don’t get close to them. Don’t spend a lot of time with them. Don’t hang around them.
We become like the people we hang around. Hang around an angry person and you become an angry person.
There’s too much to be thrilled about to walk around angry all the time.
What if you’re the angry man, though?
I guess, stop being so angry.
