my recent winter holidays were a lot of fun. i tried to visit as many places as i could and to do a lot of different things. even though the weather wasn't very nice, it didn't make me feel sad. i went to the mall and to the skating-rink with my family and friends. it's always interesting to learn something new, so i also visited the movies and watched some great films. and then, of course, there were new year and christmas, which are both my favourite holidays. we had a gorgeous christmas-tree decorated with toys and christmas lights. on the first day of new year i got many presents from my family and relatives. after all, it was just great to take some time off from school and to sleep till noon. i really enjoyed my winter holidays.
