Lunch test

The next time you have dinner with someone, do this simple experience. Unwritten territorial rules state that the table in the restaurant is divided equally. The waiter always has salt, pepper, sugar, flowers and other accessories strictly in the center of the table. When dining, slightly shift the salt shaker towards your companion. Then do the same with peppermint, sugar bowl, flowers, etc. Very soon, such a territorial invasion will be noticed by your companion. He will either move away from the table to save personal space, or he will begin to move the objects you have moved back to the center.
