"Life, for them, and their circle of friends, was often a whirlwind.
"There was a whole crowd of them, they made a fine bunch. They knew each other well; taking a lot from each other, they had common habits, common tastes and shared memories. They had their own vocabulary, their own marks, their special ideas. Too sophisticated to be perfectly similar to each other, but probably not sophisticated enough to avoid imitating each other more or less consciously, they spent a large part of their lives swapping things. They felt irritated by that often enough; but even more often they found it amusing."
