There was a bitter old woman who scowled at me in passing.
What cause do you have to be bitter? I asked her. It seems unfair to be bitter without a cause.
Do I now need a reason to be bitter? Who are you to demand this of me?
It is wrong to scowl at passerby, I insisted. I know this because I am a passerby and you scowled at me.
A child presumes to lecture me, she laughed. That is why I am bitter.
I smiled. You are laughing, so you must not be so bitter after all.
No, I am twice as bitter now because you made a bitter old woman laugh.
