A compendium of ways not to behave at a dinner party:

Berg — only talk about your achievements

Marya Dmitrievna — only make fun of other guests

German-Governor — only study the food and drink

Natasha- stare infatuatedly across the table

Sonya — listen jealously to a conversation that you are not part of

Is Pierre making full use of the occasion — looking at the faces of people who are new to him, and eating and drinking everything on offer?
