I miss quarterly visits with a friend in a town midway between us. Just us in a hotel room, watching movies, going out to dinner, looking for new places or revisiting the old, chit-chatting away. We still communicate now but it lacks the spontaneity of our usual routine.

On a weekly basis, I miss "camping out" at my Starbucks and reading, growing slowly more wired on caffeine. This is the lack that seems to have put me off of my game the most, despite it not having a whole lot of personal interaction.
