The song tells a heartbreaking story that Smith observed first hand. "It's about a marriage that I've been an observer of," he explained to Digital Spy
. "I put myself into the woman's shoes."
"The person I wrote it with, we both knew them and we just vibed off each other," Smith added. "We both had really strong opinions on what the woman was doing. It's quite a complex song. When you listen to it you think it's just bashing a guy for cheating, but it's not, it actually talks more about how the woman's a mug. She knows she's not the only one, but she's never going to leave. I think that's wrong."
