"Cardigan" by Taylor Swift is a song about a lost romance and why young love is often fixed so permanently within our memories). The song is one of three tracks on the album "Folklore" that depict the same love triangle from three different perspectives at different times in their lives, the other two being "August" and "Betty"). The young woman in "Cardigan" who is haunted by the memory of her first loves infidelity is not Taylor, but a character named Betty. Taylors latest album is not as autobiographical as her previous albums have been. For "Folklore," she has chosen to primarily tell stories that either belong to others or to characters that she has created.
