“Overall, the album is about how we all go through difficult experiences, whether it’s ending a relationship, losing a job, or just missing someone,” Lavigne says. “We get through it and we grow.” Nowhere is this feeling better expressed than on “Goodbye,” a delicate piano-and-string ballad that closes out the album. “’Goodbye’ is the most raw and vulnerable track I’ve ever written and recorded in my career,” Lavigne says. “It’s a very special song because I wrote and produced it myself. It’s so real and truthful. You can’t fake that.”
