My name is Mark and I like New Year. At New Year shops are full of people. They look for the best presents for family’s members and friends.

We usually start to decorate our house on 20th December.

The weather on New Year’s Eve isn’t too cold. But sometimes it can be snowy and at this time everybody is happy and can play snowballs.

My mum gets up early in the last morning of the old year and begins to prepare for holiday. She makes special dish. We help her and that’s why I and my sister clean the house. Father at this time usually watches old films on TV and goes to the baker’s to buy bread and sweets for us.

I like New Year because our family gathers together in the living-room and we exchange presents. At 12 o’clock we listen to our president, than we go to the street to watch fireworks display. It’s my best holiday.

I wish you happy New Year!
