Half of My Heart (feat. John Mayer)

This writes "divided attention": the person's here, but only half the heart is given. Haven't you, in a bond, known the guilt of "I couldn't give it all"?

The duet with John Mayer is both admitting "I kept half my heart for someone else." Taylor writes that honest helplessness without blame. You'll remember someone you also couldn't fill.
