sending an email in anger

never a good idea is it

No. I’ve only done it a couple of times. Objectively it would have been better not to, although I wouldn’t say I actively regret it as both times it was deserved.

Would you have said what you wrote in the email face to face?

If so, fine. Why shouldn't you be angry with someone that has made you angry?

(assuming email really is a passionate tour de force)

My angry emails are literary masterpieces. I looked back at one recently and was quite pleased. It was like a sergeant-major's invective of creative swearing. I mean, there was no swearing, just outraged bafflement.
