This was Polly Scattergood's debut single. She explained to The Guardian September 16, 2008 that the song refers to, "a friend of a friend who was really sick from cancer, this young guy who was only 30 and had a great, happy life but was slowly deteriorating. It's about the fragility of life."
Even though the song's subject matter is the singer's realization that nothing is forever, Polly believes the lyrical content to be upbeat. She explained to The Sun March 6, 2009: "It's not a sad song about death or anything. It makes me smile and think of the people I love. I find it a happy song."
