Dear Phillip, 
Merry Christmas and Happy New Year!  Be happy, merry, wealthy and healthy!
May all your dreams come true!
Thanks for your letter. Yes, we will also have school winter holidays but they are in January. You ask me about my holiday plans. Well, they will begin with our school New Year's party, then seeing the New Year's Day in with my family and relatives. I'm looking forward to recieving holiday presents and to all those delicious things that mum and granny usually prepare for our family New Year's party. Then I plan to spend a lot of time with my friends outdoors.
Unfortunately, I won't be able to sleep late in the morning because I have to walk my dog in the morning. Before or after lunch time, it depends on the weather, we will go to the park to ski. Sometimes we'll go to the skating-rink to skate. If the weather is warm we can play snowballs or make a snowman.
If the weather is cold we'll have to stay at home. We may listen to music and play computer games at somebody's home, or we may go to a cafe to eat pizza. I also like to play chess with my friend or to listen to him play the guitar. Of course I'll have to help mum about the house and go shopping sometimes...
I always plan to study English during the holidays but no time at all for it...
That's all for today. Keep in touch. Write about your Christmas holidays)
Best wishes,
