As we know there are a lot of holidays which are celebrated by families. For example, some international holidays like new year or international women's day. As for me, I like our traditional holiday - Christmas. Christmas is always celebrated in our family. We all gather around the table. My siblings also visit although they are already married and live in another city. They bring presents to us. I with my mom cook the most delicious food for a party dinner. My father with my little sister decorates the room until the party. Then they help us. After having dinner we hand our presents to each other. Moreover, we dance and play some interesting games. So, that's why it's my the most lovely holiday at all
