Brother, why did I hear fire trucks last night?

Because a house caught fire. The wiring of their smart curtains broke.

Curtains can catch fire too? Aren’t they supposed to be smart?

No matter how smart an appliance is, if it’s used for a long time or improperly, it can still be dangerous.

Then should we be worried about our robot vacuum?

That’s why you should unplug it after charging and keep it away from paper and fabric.

Got it—safety comes first, right?

Exactly. Convenience is important, but safety matters more.
