Reba McEntire rarely writes her own material, making her songwriting contributions exceptional. Her 2010 album 'All The Women I Am' included just one track she penned, 'Somebody's Chelsea,' which became a single the following year. The inspiration struck while watching 'P.S. I Love You,' where McEntire observed a scene involving a character expressing attachment to a deceased spouse, with Harry Connick Jr.'s character expressing a desire to become that person's beloved.

McEntire collaborated with Liz Hengber and Will Robinson to develop the concept into a complete song. Robinson noted his surprise at the originality of the idea and acknowledged the creative challenge of building lyrics around an unconventional title. Rather than directly mirroring the film's storyline, the writing team reimagined the narrative to centre on an older man reflecting on a six-decade marriage, creating a composition that captures the universal desire to be someone's most cherished person.
