Recently, while enjoying a five-minute lunch break of Fritos and a Slim Jim at my desk, I heard the joyful laughter of a group of summer campers and their counselors heading off for an afternoon of lunching.

Was I jealous of their frivolity? Envious of their carelessness? Bitter that I was not invited? Nope. I was grateful I was taking care of my biological need to feed my brain without losing two solid hours of billing time. Don’t get me wrong — every now and then I indulge in an hourlong lunch break over a sandwich with an old pal, heading into the open air for some salad and socialization. But the days of daily group lunches are a distant memory.
