talking about a party you attended:
I have joined many parties in my life. Last month was my Nan's birthday, Whom is my cousin. My uncle organized a small but warm party for him. His mother prepared a beautiful birthday cake for him too. I was invited to that party. The party started at 7 p.m. The birthday cake was displayed prominently in the middle of the table. Our family gathered and sang " Happy birthday" song to him.Then, He wished something, blew out the candles and took a knife to share cake for everyone. After that, people gave him present and I gave him a book which he like. Suprisingly, his father had a special gift for him, it was a sport shoes because he like play football. He was ecstatic. There was a lot of fruite and refreshment. we ate, listened Pop songs and danced together. the party finished at 10p.m, think that is the memorable party I have attended
