Bryan Vartabedian on the angry email:

The angry email is usually rooted in frustration over inefficiencies or some nagging problem that hasn’t been fixed. Ultimately, it’s about the fantasy of the willful imposition of change by the sender. […] The defining element of the angry email is that it’s ultimately regretted. Or it should be.

I’ve written thousands of angy emails in my head, a dozen or so on the computer, and sent zero to date. If there is a next one, I’ll write it in longhand.
