This song finds Ed telling the story of the first time that he realized he was in love. "Your body is my ball-point pen," he sings, "and your mind is my new best friend." Like many of the songs on +, this was inspired by a teenage romance. "I had a wicked girlfriend at 17. ... She was great," he told MTV News. Actually [my] + album is pretty much about her. So she spawned off a lot of songs."
