You might need that bridge again. Walk away without setting it on fire.

Endings tempt you toward the final word, because you are leaving and the consequences look like they are leaving with you. They are not. Fields are smaller than they appear, people move around inside them, and the person you shouted at turns into somebody’s colleague or somebody’s reference. A dignified exit costs you one satisfying speech.

Write the angry message if it helps, then do not send it. Say the plain version instead: thank you, here is what I was in the middle of, good luck. Then go.
