Suppose you are an employee of a firm and you have a meeting tomorrow at 10 am and you set the alarm for 7 am but but you are very tired and you mistakenly set the alarm for 8 am. When you wake up next day, you take a look at the alarm clock, and get scared thinking how angry your boss will be and you have to explain this incident to your boss. How will you explain it?
