The speaker writes a letter to Lauren, another girl who seems to have been hurt by the same man. The poem hints at violence and abuse without spelling it out, and the speaker's own memory of it has become a blur. She describes how he turned Lauren from someone bright and golden into someone worn down, and she links them both to a "sisterhood of broken girls."
What drives the poem is guilt. The speaker believes that if she had spoken honestly and pushed harder, Lauren might have been spared. She says she tried, but the officials who could have acted hid behind procedure, and she is furious that they treated "bureaucracy" like a fair answer to what she had endured. She also blames herself for downplaying what happened at the time, saying it was "no big deal."
The mood is raw, tired, and tender. The ending is the most striking part: she offers to "take the fall," ready to carry the blame so Lauren doesn't have to while she works out where it belongs.
