It’s possible that Charles Dodgson (aka Lewis Carroll) was writing about email when he penned these words of wisdom in Eight or Nine Wise Words About Letter Writing in 1890. Now, how do I go about sharing it with the author of that flamer I received the other day?
…when you have written a letter that you feel may possibly irritate your friend, however necessary you may have felt it to so express yourself, put it aside till the next day. Then read it over again, and fancy it addressed to yourself. This will often lead to your writing it all over again, taking out a lot of the vinegar and pepper, and putting in honey instead, and thus making a much more palatable dish of it!
