It might be a spouse, a girlfriend, a marketing pany, a boss, a cop or　　a criminal. Whoever it is, they will see you in a way you never intended to be seen—the 21 st century equivalent of being caught naked.　　Psychologist tell us boundries are heathly, that it’s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where yo are and what you like. In some cases, a simple Google search can reveal what you think.
