There are a couple of scenes in the movie Broadcast News in which Holly Hunter lets off steam every time she's emotionally overwhelmed.
She goes off alone and bursts into tears for a brief period, less than a minute.
Then she composes herself and re-enters the present.
I think I was the prototype for that character, except, sometimes, I don't have the control to save it until I'm alone.
When I am feeling like that, all it takes is someone saying to me, "What's wrong?"
The brief tears are an emotional "boiling over" like a pan of water on High.
Once it occurs, I automatically switch to Low and simmer. I feel totally relieved.
It used to be embarrassing, though I'm used to it now. I don't think I've had a boss, friend, or relative who hasn't seen me cry like that.
If I could turn the angry tears into a well-thought-out argument, I'd probably be further along in my career.
