Hussain gives a voice to a stray animal, most likely a dog, that has learned to read people's faces even though it cannot understand their words. It sees disgust and hears shouting, and it knows it is unwanted. The speaker doesn't rage back. Instead it asks quietly why it should be blamed for being abandoned, unwashed and left to fend for itself.
The most painful moment comes when the speaker recalls its father lying under the tyres of a car, while the driver simply passed by. Still, the animal is grateful to the few who feed it, and it hates that they get mocked for their kindness. So it chooses to roam and find its own food, sparing them the insults.
The mood is sad but gentle, close to pleading. The final lines ask humans to work toward a better place for animals like this, and the closing note, "unspoken words," reminds us that the animal can't say any of this aloud.
