The girl in the dress, cried the whole way home / I should’ve known", goes the lyrics of Dear JohnWell, maybe it’s me / And my blind optimism to blame / Or maybe it’s you and your sick need/ To give love then take it away / And you’ll add my name to your long list of traitors / Who don’t understand.”During an interview with Rolling Stone, John Mayer called Taylor Swift's song writing as cheap."I felt awful about it. Regarding Swift supposedly penning a song about him, Mayer told the magazine in June 2012, "It was a really lousy thing to do." "I never received an email. I never received a call. That's exploiting your gift to rub your hands together and say, 'Wait 'til he gets a load of this!' I was truly taken by surprise. That is nonsense.In the end, Taylor Swift rerecorded "Dear John" for Speak Now (Taylor's Version) and advised her followers not to rekindle their animosity toward Mayer.
