During a concert in Winnipeg, Manitoba, the Canadian rocker told her audience that "Wish You Were Here" was about missing someone. "It's something we all go through in our lives," she added. While many fans assumed this regretful song was about her recent divorce from Sum 41's Deryck Whibley, who produced half of her Goodbye Lullaby album, Lavigne told Rolling Stone the songs on Lullaby were not breakup tunes. "People will make assumptions, but they'd be surprised what certain songs are about," she said. Still, this song's vulnerability marked new territory for the normally feisty pop-punker.
