Timer

Some people are so technologically inept that they are incapable of operating an alarm clock. Such a person might choose to use the kitchen timer (25' from her bed) to set an alarm on those rare days she needs to be awoken early. But then when somebody decides to set the kitchen timer for a perfectly reasonable use (timing the oatmeal or the brewing tea), it can sure jolt a technologically-inept person awake FAST, and set her to wondering WHY she's supposed to be getting up right now.
