Family is an integral part of every person’s life. It is the most important social unit. A sense of stability and tradition, that family provides, can’t be replaced by anything or anyone. Perhaps, every family follows some special traditions that have been passed to them by former generations. My family is not an exception. For example, in my family it is habitual to dine together. Every evening, when my parents come home from work, we have a nourishing family dinner. First of all, it lets us feel a close unit. Secondly, we get to discuss the important events of the day. The same tradition can be seen in my grandparents’ house. Other than that, we are used to share the household chores. Everyone has its own duties. For example, my mum is responsible for cooking, while my dad always does the shopping. I’m responsible for the pets and plants, while my older sister is responsible for washing the dishes and vacuum-cleaning. In my opinion, we are a close-knit and friendly family. Each time there is an official holiday we invite the friends and arrange a posh feast. We especially like celebrating New Year and Christmas. The traditional New Year dishes in our home are a roast chicken, a couple of Russian salads and my mum’s specialty - a vanilla cake. We always prepare postcards and presents for everyone who visits us and for our family members. The presents are usually placed under the Christmas tree. Other family tradition is going out on Friday nights. Every Friday we go out for a dinner. After that, we either come back home to watch a good movie, or we go to the cinema. There are lots of other traditions in my family, but these seem to be the most important ones.
