A family tradition can be called the customs and traditions that are moving in the same family from one generation to another. The family values and traditions, habits are different our family. After all, everybody has their own. For example, among the traditions of my family, such as joint modeling of dumplings for the New Year. The holidays are celebrated in different ways, but in our family every year all looks the same. We all together make dumplings, celebrate the New year, watch TV. And though none of us no longer believes in Santa Claus, we give each other gifts, and put them under the tree. I like the fact that we not only comply with these family traditions, but also get pleasure from it, even adults. And similar traditions in our family a lot. For example, we do General cleaning every Saturday. Each family member has their own responsibility to dust, sweep or wash the floor. In the evening, after General works, we love to sit the whole family and watch something interesting on TV. And this is also one of our family traditions. In addition, we love to gather the whole family outdoors on the 9th of may. We celebrate Victory Day, remember our ancestors who participated in the great Patriotic War. Unfortunately, most of them died. But we remember them and honor the memory of our heroes. And this is a favorite family tradition of all that met my family. When I will create your own unit of society, I would really like to move all those family traditions that I have followed since childhood. I want my children and grandchildren have followed them. Family traditions are a huge and important value of each family.
