Fire? No, just cooking...

I was making lunch, and the kids were playing downstairs. Our smoke detector seems to be highly sensitive, so almost every time I cook, it starts beeping. I have to wave something under it to clear the air. Since it's such a common occurrence, the horrible beeping rarely elicits any response from the kids. Today it was blasting away, and I hadn't had time to stop it, so after a few minutes, Noah yelled up, "Mom, are you cooking, or should we evacuate?"
