n. The fear that your connections with people will keep dwindling as you get older; that one by one, you'll all go flying off the merry-go-round in wildly different directions, sailing through various classes and jobs and interests, ultimately landing in far-flung neighborhoods where you'll hunker down with your families plus a handful of confidants you see a few times a year, perpetually reassuring each other, "We should keep in touch."
