难忘的一件事_700字

July 2 is my grand father's birthday. On that day, all of my families will get together to celebrate his birthday. This year was the same. My uncles and aunt came back from other cities. It was so alive that my grand parents were very happy. This year, I made a surprise for my grand father. I cooked a dish for him. As I never cooked before, he was so surprised as well as exciting. My grand father said that it was the best birthday gift he received. I was glad to make grand father happy. Actually, I had practiced for several days before that day. My mum was my cooking teacher. She supported me to prepare this gift to grand father.
