This ballad was written after the end of a relationship. Nutini told The Sun: "People change. I don't know if I'm changing for the better or for the worse."
"I don't think I'm any more reliable than I was when I was 19," he continued. "I certainly don't feel like I'm taking this anymore in my stride than I used to. That song is about appreciating being with somebody, rather than feeling restrictive and tied down. But it's just my perspective."
Nutini previewed the song at a gig on February 11, 2014 at north London pub the Boston Arms. He introduced it by saying: "'That girl, she makes you want to be a bit smarter. Or a bit better."
