What do upper-class people usually do? What are you playing? What to eat? In and out of what occasion? What kind of friends do you make?
Usually very casual, but there are endless papers. If you play more, your personality will be different. There are also many private parties, eating health food, going in and out: generally, they are relatively advanced private clubs, and the friends you make are just eight words: birds of a feather flock together, and people are divided into groups.
