Проверьте как я написал сочинение и есть ли ошибки? My holidays began on the 28th of December. I am in a good mood because New Year’s Day and two weeks of the rest will come soon. I like festive bustle. In the first day of our holidays I and my sister decorated our flat and we also decorated the Christmas tree in the evening. In the first day of January we went to celebrate our grandmother and grandfather and next day we went to street festivities at city square. The whole holidays I and my sister were spending much time in the street. I liked my winter holidays very much.
