Long letters are not dead. I have a short list of old friends whom I communicate via the infrequent long email only. These are old acquaintances with whom I have no regular business with, and they have moved far away in life, so short texting conversations are irrelevant. Usually I initiate these "pen pals" by reaching out on Christmas or Eid, several years after we have lost contact, and I make it clear to them that I want to maintain infrequent long correspondence. Usually they are overjoyed and respond with great enthusiasm, as they may have never received or written a long personal letter before in their life. It often has a powerful effect on people. In terms of content, I try to avoid making the letter too personal, because we have been far separated in time and place, sharing only major milestones in life. The fact that I don't use Facebook or any social media at all helps, because people have NOT seen what I've been up to, nor have I seen what they have been doing. I believe the long letter works better than social media -- you can maintain deep, meaningful relationships, with people far away and long ago, with people of the same and opposite gender, without getting involved in the muck of social media.
