My Last Winter Ilolidays
I spent my last winter holidays in Moscow. This year I did not go anywhere. First!
thought it would be dull to stay at home. But how it seems to me they have been one
of the finest holidays in my life. May be that's because they were our last winter
holidays at school but all the same we had a lot of fun
Our winter holidays began on the 27th of December. On that day we had a New Year
party at school. Certainly, we had been preparing to the party for long time
beforehand. We had prepared an amateur performance with Father Frost and Snow
Maiden. There were different competitions, we played different games. Certainly the
lucky winners of the memorable prices. We had prepared them before and bar we
had not bought them
We had trought some nice trinkets from our homes. Those who won these prizes said
that they are especially dear to them because they would remind them about their
schoolmates. Then we had a dance party. That day we had a lot of fun
I like winter for a xumber of holidays we celebrate at the beginning of a new year,
Alex, 12 Moscow
