It was a sunny day yesterday. Peter 1 to see Daming. He had a birthday gift for Daming. Daming was surprised because it 2 his birthday. At that time Simon 3 back, with some birthday cards in his hand. "Oh, it's Simon's birthday today! I remember." said Peter. He gave the birthday gift to Simon and 4 , "Happy birthday, Simon! I thought it was 5 birthday today." Peter made a mistake (错误) but he was happy. They all laughed over it for quite some time.
