Tahlia's poem turns the walls of a home into silent witnesses. They can't speak, but they hear everything: the lies people tell, the truths they hide, every slip and fault. The speaker's central idea is that silence isn't the same as harmlessness. Because the walls never answer back, they seem wise, but they also seem sneaky, even like "demons" waiting to catch someone out.
The speaker sounds uneasy, though also protective. The final lines shift into a gentle warning, "speak softly my dear," as if advice from someone who knows how easily words can be overheard. The poem never says whose secrets are at risk, so the reader can imagine a family, a friendship, or private guilt.
The mood is hushed and slightly eerie. Repeated phrases like "These walls" and "Who knows" work like whispers, building suspicion. The simple rhymes and short lines make the poem feel like a quiet caution passed along in confidence.
