Digital permanence makes temporary emotion unusually durable.

Things once said in a moment and then dissolved are now stored with a timestamp. A bad night, an opinion you have since abandoned, an argument that was over by Thursday. Human emotion is designed to be temporary and the record is not, and the mismatch causes real harm.

Wait before writing anything while you are hot. Not forever, just long enough for the feeling to change shape. Almost nothing worth saying is lost by a delay, and quite a lot that would have been permanent is.
