Virginia Woolf’s serious joke that “on or about December 1910 human character changed” was a hundred years premature. Human character changed on or about December 2010, when everyone, it seemed, started carrying a smartphone. For the first time, practically anyone could be found and intruded upon, not only at some fixed address at home or at work, but everywhere and at all times. Before this, everyone could expect, in the ordinary course of the day, some time at least in which to be left alone, unobserved, unsustained and unburdened by public or familial roles. That era now came to an end.
