i have many hobbies, such as playing computer games, reading comics, going shopping. i also like playing pingpong very much. i have a friend. his name is nick. he is crazy about playing pingpong, too. if we have free time, we often play pingpong together. one summer holiday, he took me to a sports centre. then we played pingpong together, but he always lost. he was very angry. he said to me, "i will beat you in a month.""ok. we will have a match at that time."after a month, when i talked to him about it, he answered,"i forgot the thing! i don't want to have a match with you." i was very surprised and angry and said,"oh, you're a forgetful boy!”
