Writing letters and not sending them.
Writing an e-mail that’s not meant to be sent has many advantages. I do it all the time, personally. We can let go of our petty, personal vitriol - the things that we plan to say to prove our superiority over the worm in question, this snake in the grass that has caused us such pain. We say these things and then never have to say them again, unless they really were necessary. It’s easy to see when things are written down which ones need to be said and which ones can fade into our memories. They’re placed in a context and the bigger picture is apparent. In this way we can preserve good relationships.There are two main dangers with this approach. One is that, in pouring out our guts and then deleting it, we might forget something important - something that DID need to be said and will now be forgotten because the hurt is gone.
The other danger is that we might accidentally hit send.
