Pictures.

“In the old days, when you eventually got your pictures back from the drugstore, you never went backward through time. You shuffled through the twenty-four holiday snapshots, only seven of which were any good, put them in a drawer and forgot about them. You didn’t have t compare them to every other holiday you’d had in the last seven or eight years. But now she couldn’t resist it. When she uploaded or downloaded or whatever it was you did, the new photos took their place alongside all the others.”

 (Nick Hornby – Juliet, Naked)
