You just have a lot of work pressure, now is the time to relax. You are thinking about a new bubble bath from Bath and Body Works all day and how great it will be after a long day. You get inside the door, take off your shoes and start to warm up, and you can imagine the relaxed feel you already feel. Someone went to work this morning, but I did not notice that I forgot to pull out the hair dryer. When I entered the bubble bath of the chemical cabinet, I accidentally put the dryer in the bathtub water.
Common sense is necessary * You should escape from the bear. No, in common sense that you will die, you need to water the fire of electricity. No, the common sense that you die will be safer than a stranger than a stranger family. You are different. Common sense demands your anger is good for you, that time will be handed to anyone at the same speed no matter how fast you can, you can determine the speed and position of the electron at any time. From a common sense, you are asked not to inject the mild sick people to prevent infections of potentially fatal types.
Your common sense may not be with other people. We hope to use common sense for people and use it in everyday life, but nothing common in common with this common sense. The principle of hospitality seems to be radical in places where people do not expect to pay much attention, but for the Japanese it is part of it. A commonsense problem is not that it is irrational, but something sensible depends on many other features of the situation. In general, it is not until after the event which of these many potential features are related (philosophers and cognitive scientists call the "framework problem" a fundamental problem).
