How do you celebrate your birthday? (5-7 предложений)

Dear Martin,
 We usually arrange a birthday party on Sunday. 
I invite my relatives and my best friends. Mum and I clean the flat on Saturday.  There are usually a lot of balloons in the room where the party is.  A big cake with candles is usually made by my granny. At the party there is always lots of delicious food and drinks. My friends come and I get a lot of presents from them and from my  relatives.  When tea time comes I make a birthday wish and blow  out the candles on the cake!   We dance and sing. Then we play games. We also organize  interesting competitions. We enjoy the party and have fun. Birthday parties are great fun for everyone! 
You asked me what present I would like to get for my next birthday. I think it will be a mountain bike. When is your birthday? How did you celebrate your last birthday? What would you like to get for next birthday?
Keep in touch.
Best wishes,
Oleg
