Why didn't the smoke detector go off?

My entire home smells like a burnt offering to the gods. How was I to know that microwaving a piece of corn bread for too long would cause it to emit dense yellow smoke that engulfed the entire place? The only thing I was panicking about was that the smoke alarm would start blaring and the entire neighbourhood would come to see what was wrong.

But no. It remained as calm and serene as ever. I could not see my hand in front of my face, the smoke was so thick. But the detector cared not. Detached objectivity seemed to be its motto. Eventually all the smoke cleared off. But it's two days now and my home still smells like I've just had an ashwamedha yajna done.
