See big or small, human relations is what are the most meaningful.
My class mates and I keep up via email (used to be snail mail, though I get on a writing kick every now and again and still send out the occasional letter) and other ways but nothing is so good as just sitting there, looking around the table at the faces of people who know me. We don’t have to say a thing. We all understand
Nothing replaces seeing someone and talking and interacting with them in person.
