You've Got Mail

I may have already quoted this, but:

Joe Fox: Do you ever feel you've become the worst version of yourself? That a Pandora's box of all the secret, hateful parts - your arrogance, your spite, your condescension - has sprung open? Someone upsets you and instead of smiling and walking away, you zing them? "Hello, it's Mr Nasty." I'm sure you have no idea what I'm talking about.
Kathleen Kelly: No, I know exactly what you mean, and I'm completely jealous. What happens to me when I'm provoked is that I get tongue-tied and my mind goes blank. Then I spend all night tossing and turning trying to figure out what I should have said. What should I have said, for example, to a bottom dweller who recently belittled my existence?
[stops and thinks]
Kathleen Kelly: Nothing. Even now, days later, I can't figure it out.
Joe Fox: Wouldn't it be wonderful if I could pass all my zingers to you? And then I would never behave badly and you could behave badly all the time, and we'd both be happy. But then, on the other hand, I must warn you that when you finally have the pleasure of saying the thing you mean to say at the moment you mean to say it, remorse inevitably follows.

...I'm never going to be able to find a balance between the two, am I?
