A friend of mine, a great cook, regularly performs what she refers to as The Dance of Smoke Alarm Supplication, wherein she and a broom jointly try to persuade the alarm gods that everything is fine. When she heard that there was a smoke alarm that would pop up a notification on her phone first so she could mute it with zero shrieking, she was very excited.<p>It may be that her landlord installed it wrong, but landlords (and homeowners) install an impressive number of things wrong, so a business that didn&#x27;t depend on &quot;amateur does X perfectly&quot; doesn&#x27;t sound like a bad idea to me.
