“I come from a generation for whom the books and records on the shelf signaled, in some way, who you were. If you visited a friend, you took the first chance you had to surreptitiously scan that friend’s shelves to get a handle on the person. I suppose I could sneak a peek at a friend’s Kindle, but is that the same? And try that kind of snooping on a bus or in a coffee shop and you’ll probably get arrested.”
