So I always thought everything that beeps and wakes you up at night or in the early hours is somehow important. And also annoying. Fire alarms, smoke detectors, those carbon monoxide detectors, all of them are equally important yet no less annoying.
Today I arose to search for and discover that the high pitched ‘beep-beep’ is caused by the refigorator complaining that the temperature inside is getting too warm. It’s one of the variety of sounds I didn’t even knew the fridge made. It also beeps when you leave it open too long.
Now I would just call that annoying.
