We've all seen this. Heck, we've all done it.
Somebody starts to complain about something, something they've complained about before - perhaps often - and we feel impatience rising up inside us. Not this again, a cranky voice inside us sighs, and maybe we even sigh on the outside. And we catch the eye of somebody else and see that they are sighing too, and we share that look, a very meaningful look. A look that everybody recognizes when they see it.
It's the "Here we go again" look.
