Janie: Our team lost the relay race on the sports day. It’s a really bad experience! Cindy: Hey, don’t be sad. We always have to look on the bright side. Cheer up! Janie: But my teammates said that I was too proud to work with them. I think I led them to the failure. Cindy: Don’t be upset. I can try my best to help you win next time!
