The poem takes the old childhood rhyme about sticks and stones and quietly shows how wrong it is. The speaker wishes it were true that words are empty, but online cruelty clearly hurts. It stings, the speaker says, because hateful comments get twisted into something that feels like the truth.
Most of the poem turns to a girl who feels like "an outsider in her own home." The speaker defends her, telling the attackers they don't know her story and that she isn't their "entertainment" or an outlet for their anger. Screens, described as "glass that is not see-through," let people forget there is a real person on the other side. The wing imagery, "clipped, shattered," suggests she has been badly damaged.
The refrain "If only it were true" returns again and again, shifting from wistful to weary. The mood is sad and protective, with a flicker of anger. The ending, wishing the walls had fallen long ago, leaves the hope unfulfilled.
