I have boxes of incriminating teenaged letters from a flock of far flung friends. I would never throw away a true personal snail mail letter.
I keep the emails of my really good friends in the same way I would save their letters. I’m not really likely to read many of them again, but I think they may be of interest at a later date, especially to their children, if they don’t save their own “sent” emails.
Emails that are merely scheduling or strictly business get deleted, but even relatively insignificant short ones get saved if there is anything humorous or conversational that reveals the personality of the sender and they are close to me.
How about you?
