 I was born on the 12th of March. Birthday is a very remarkable day for me. March is a spring month and usually the weather is warm. In the morning my parents come to my place and say: "Happy Birthday!"

They give me presents. I enjoy getting them. Most people have a birthday party on this day.

This year I have my birthday party at home. My parents and I prepared for this day. We invited my friends and relatives to the party.

I celebrated my birthday on Sunday. I got up early in the morning. My father and I went to the shop and to the market to buy everything we needed for the party.

My mother stayed at home. She made cakes and laid the table. At four o'clock my relatives and friends came to congratulate me and I was glad to see them. They brought flowers, books, sweets and presents. I thanked them all.

We had a good holiday dinner on this day. During our merry party we sang songs, danced, made jokes and spoke about our life, hobbies, and future.

I enjoyed my birthday party.
