“When everyone else attended a birthday dinner together, I was met with excuses as to why I hadn’t been invited. I still don’t get why I wasn’t at the girl hang that they all planned at my daughter’s birthday,” she wrote, before accusing the group of having a “pattern of leaving someone out.”

“During the early days of the group, there was another mom who often wasn’t included. I’d picked up on hints of a weird dynamic, but at the time, I didn’t dwell on it too much. I was just so happy to have found these incredible, smart, funny women. Now it seemed that this group had a pattern of leaving someone out. And that someone had become me,” she claimed.

“The song is about reflecting on your past and coming to terms with the choices you’ve made, but without being too hard on yourself,” Hilary explained to Vogue. “It is definitely about a brief experience that I had in my — a long, long time ago. But it is not totally autobiographical. I took a few artistic liberties just to make the song work structurally, but the gist is the gist.”

“I was looking back on this relationship and thinking about whether this guy had a habit of dating younger women or whether I was ‘special.’ The whole experience was super therapeutic to write about, but being so vulnerable through your music can be really scary,” she said.
