It's great when you have the opportunity to catch up with a one friend from an old group of acquaintances. That friend can fill you in on everything that's happened over the last couple years as if it all happened on one day. "So-and-so quit his job, someone got beat up in a bar, then another person got a dog and gave it away a week later". All the boring parts are edited, and it's like everything fun happened on one super action-packed day. It's the only upside to being bad about keeping in touch with old friends.
