I had a long phone chat with a friend and former roommate from grad school this morning, and it was just great to talk. We haven't much talked for years, not because we had a falling out or anything, but because other things happen, and we're both busy, and so on, but talking was great, and I hope we talk more sooner rather than later.
This roommate was one of the sanest, most common sense, down to earth people I knew in grad school. She was really smart in all sorts of ways, but also really decent and thoughtful.
Of course, chatting with my former roommate also got me thinking about some other grad school folks, many of whom were (and are) wonderful in their own ways, but few of whom I have much contact with these days.
