Take a rest is the best!

People can not be in a good mood all the time. If you pay attention people, sometimes they are in a bad mood. When they are in a bad mood, they generally need to stay alone. They do not want to do anything. I like staying alone sometimes, because I can think over better for an important issue. I can focus on my subject better. For this reason, I prefer to study alone. Moreover, I like staying alone, because it means that there is nobody to cause a problem. Take a rest is the best way to recover energy. It is not strange to me to isolate myself from the world for a while. I think, it is a good way to get rid of stress.
