ДОПОЛНИТЕ ТЕКСТ, ПОЖАЛУЙСТА. ЗАРАННЕЕ СПАСИБО. In Belarusian villages people had strict table manners which they taught their children from an early age. They could take a spoon only after they (1.wash) their face and hands. The father took the most important seat- at the head of the table, then the older children sat next to him; after them, the younger ones and, finally, the mother who (2. serve) the dishes. The children served themselves only if they (3.learn) to use a spoon. Without saying a word, the father cut the bread and gave out the slices to everyone. Only after he (4. spoon) some food out of the pot standing in the center of the table, the other family members could do the same. Soup or stew was often the main dish so the children were taught to carry their spoon from the pot to their mouth over a slice of bread so that they (5. not spill) it on the table. The family had to eat all the food on the table without any leftovers. The parents told their children that the leftovers (6. come) to them at night and wake them up if they didn't eat all the food. People ate slowly in silence so that they (7. not choke '). In the end, everyone put their spoons on the table after they (8.lick) it clean.
