Back in my day, during freshman year in college, I remember receiving mail—as in the handwritten, signed, sealed, and delivered variety—from about 15 of my friends from high school. It was reassuring, and entertaining, to hear of the continued boneheaded exploits of a group of friends with whom I had grown up. While written communication was not transmitted on a regular schedule, we did, on occasion, “instant message” via our landline telephones and share our “likes.”
