Don't you think it's useful if we have a alarm clock which sounds earlier than set time and its hands are masked so that we can not know what time it is. We can not fall back to sleep because it might have been running late already.If we leave home earlier as a result, we can go to cafe to read a book. It will help us to get away from every morning routine.
