Marjorie Finlay was Swift's maternal grandmother. The two shared a bond over music. Marjorie herself was an opera singer, The Independent reports. "She was actually a recording star in Puerto Rico when my mom was growing up," Taylor once explained of Marjorie, per GoodReads. "My mom was always stuck sitting backstage somewhere or sitting in a front row, watching a performance her entire childhood. She thought that when her mom stopped performing she was relieved of those duties, but all I wanted to do was sing, ever since I was born, so she's always been backstage."

Marjorie's vocals are featured in the background of the track, making it extra poignant and emotional for both artist and listener. Swift sings a beautiful tribute that's also got a hint of mourning. Marjorie died in the singer's hometown of Reading, Pennsylvania, in 2003. Swift was 13. The song features Swift's favorite lyrics from the album, as she revealed during a YouTube live session marking its debut. What many believe is sage advice Marjorie imparted on her granddaughter: "Never be so kind, you forget to be kind/ Never be so clever, you forget to be kind" (via Genius).
