When you’ve known depression, I think, the little up-and-down moods of daily life can scare you. It’s hard — but important — to remember that you can get sad from time to time without plunging into an emotional tailspin with no apparent bottom.

That’s about all I have to say about this. My son Matt left town yesterday for home in Virginia and my son Tristan is leaving to visit his girlfriend in New York before heading back to college. Callie, my daughter, called from the airport last night while waiting for a flight to Paris. Sometimes I miss the days of their childhood so much it’s hard to imagine how I can live without them — even though I’ve been doing it for a while now.
