My classmates billy changed .I was at a party today. I met my primary school classmates who I haven‘t seen for three years. At the party, I saw that Billy really changed a lot. He used to be very shy and quiet. When chatting with female classmates, her face would turn red. I used to see that she always studied in the library. He studied very hard and achieved many good results. In his examination, he used to wear glasses, but now he looks very strong and big! He is also very popular now. I see all the girls around him at this party.
