Facebook has officially crossed the line. It’s gone outside of its digital boundaries and violated me. I’m checking out at Best Buy and the cashier gives me a quizzical once-over. “Hey man, where do I know you from?” Internally: “I’ve never seen you before, this is awkward, just let me buy my Wilco album and we’ll pretend this never happened.” Turns out one of my friend’s tagged me in some photos from a party the night before, and now, thanks to the marvels of social networking, he “knows” me. Something tells me I wouldn’t have been as upset if this was a random hot girl.
