- One year ago, John Mayer kvetched to Rolling Stone about the "humiliation" he suffered over "Dear John," Taylor Swift's unflattering ode to their rumored late 2009/early 2010 fling. "It made me feel terrible," he said of the song. "Because I didn't deserve it. I'm pretty good at taking accountability now, and I never did anything to deserve that. It was a really lousy thing for her to do."
