The text you typed and deleted might have said more about you than the one you sent.

The first version is the honest one, written before the editing for how you want to be seen. What you removed is usually the part that was true and inconvenient, the request, the hurt, the thing you actually wanted to say. The sent message is accurate about your manners and the deleted one about your state.

Next time you delete a paragraph, read it once more before it disappears and ask what it was telling you. You do not have to send it. But notice the pattern in what you keep taking out, since it maps what you avoid.
