Ellie admitted to Spinner UK that there is a lot of her on Lights, including the questions she asks on this song. She said: "I'm quite questioning, I suppose, but then I answer the questions as well. In one song I say 'Who are we to be emotional, who are we to play with hearts and throw everything away?' so I'm questioning human behaviour, asking why we act the way we do when we're in love and infatuated with someone, but later in the song I offer some answers too. I'm a hopeless romantic, and I'm always thinking about what love is."
Ellie Goulding told Sky Songs: "This Love is about cheating on the person you're with, and questions why any of us do it."
In The Beatles "When I'm 64," Paul McCartney asks a woman if she'll still be there for him when he's 64. In 2006, he got his answer when shortly before his 64th birthday, he and Heather Mills separated.
