There are two opposite points of view on the attitude of a place you are living in. Some people consider that a room can tell a lot about its owner. However, others, on the contrary, are sure that it is impossible to know about the identity if a person according to his room.
As for me, I think that a person's room can tell and describe a person a lot. First of all, if the room is clean you can easily understand that a person is near. But, on the contrary, there are people, who never make bad or keep throwing their socks around the room. It means that the person is lazy. What is more, the room can be decorated with person's preferances, hobbies, rewards. According to them you can easily understand what the person likes. For instance, there can be different posters of favourite musicians or sport teams on the wall, which show what music or sport the human likes.
However, other people suppose that room does not show person's identity. We must admit, that a person can simply forget to clean up his living space. So an unkempt room does not mean that inhabitants are lazy and dirty. It just means that a person was, probably, in hurry and had forgotten to clean his room.
I fully disagree with this fact, because house cleaning should be a habit. If a person does not clean his room for several days, he just forgets about his charges and he should accustomed to put everything at their places.
In conclusion I would like to stress that a room is a mirror of a person's daily life, hobbies and character.
