Just by looking at a cluttered table we can determine the state of the person using it.
Even whole countries or a race can be represented by one character. The Japanese for hard work or the Gurkhas for bravery. The best representation of a man is his home where he spends so much of his time. Here he lives, loves and nurtures himself and his family's lives.
