• This was one of the first songs Lavigne ever wrote - she composed it when she was an unsigned 15-year-old living in Napanee, Ontario. "It was probably the second song I [ever] wrote; I was trying to figure it all out," she recalled to Billboard magazine. "It's really special to me."
• Lavigne said in publicity materials for Goodbye Lullaby: "Whenever I hear 'Darlin,' I think of the family room I wrote it in and playing it for my mom."
• Lavigne was always playing this song for her friends, even before she had a record deal. She told AOL Music she played it to ex-husband and Sum 41 frontman Deryck Whibley the day she met him, when she was 17 and "Complicated" was just coming out. Lavigne recalled: "We were in Vancouver with his band, all hanging out, and I played him that song and then like eight years later he produced it. He remembered it and was like, 'Let's record this song.' So we did."
