It’s a little strange that the familiar saying “good grief” is a censored form of “good God.” I suppose it dates back to when 1) saying “good God” could get you staked for blasphemy and 2) the times when folks believed God punished us with grief.
And then there’s poor Charlie Brown. I like Charlie. He’s one of the good guys. On the surface nothing seems to go his way, yet in the end, he makes it through. When Charlie gets annoyed over the stupidity of his friends, he declares, “good grief” and he keeps chugging onward.
That became one of my writing rules. When annoyed by my own stupidity, or that of others, I simply say “good grief” and keep moving on.
And on. And on…..
