Cover art for Ribs lyrics by Lorde

I think this song is about wishing you could be younger again. About the hardships that come with growing older, and all the responsibility you have on your shoulders. The second verse is about how alone she feels even though she is roaming the streets with her friends now that he is old enough to do so. I think the last verse is about wanting the old her back, the younger her. And even though she has friends that share the same fear of growing older as she does, it doesn't stop the fact that she and all of her loved ones are growing older.
