Who is Mary in Taylor swift's song Mary's song oh my my?

Answer 1

It's a song about her neighbours who were childhood friends, teenage sweethearts and adult lovers. They've gotten married, had kids, grown old together. Why would you ask why she wrote that song? Why does she write songs at all? To express herself and to tell stories. She thought her neighbours love story was romantic and it was nice to see that "sometimes love is forever", when you have trashy media or trashy teenagers forever showing failed relationships.

Answer 2

It was inspired by an old couple who had been together forever and had grown up together - I think they were their neighbours.

Answer 3

She wrote the song about her elderly neighbors and how they fell in love. Mary is the name of the lady.
