Alfred: This party is such a great idea!
Gina: I agree. It's been three years since we last saw our primary school classmates.
Alfred: It's interesting to see how people have changed.
Gina: Billy has changed so much! He used to be so shy and quiet.
Alfred: Yeah, his face always turned red when he talked to girls!
Gina: I used to see him reading in the library every day.
Alfred: That's because he was a really good student. He studied hard and got good scores on his exams.
Gina: Did he use to wear glasses?
Alfred: Yes, and he used to be thin, too. But look how big and strong he is now!
Gina: He's so popular now. Look at all the girls around him!
