Amelie: Hi Phuc! Where’s Mai? Isn’t she coming? Phuc: She said she was too tired and didn’t want to go out. She’s been staying up late studying for the exam. Nick: Does she need to be that stressed out? Phuc: Maybe not. But my parents always expect her to get good grades and she doesn’t want to disappoint them. They want her to go to a top college and study medicine. Amelie: Really? She told me she wanted to be a designer… Phuc: Yes, that’s why she’s been a bit tense lately. She doesn’t know what to do. Her parents said design graduates wouldn’t find jobs easily and they wanted her to get a medical degree. Amelie: Oh, I understand. Sometimes I wish my parents could put themselves in my shoes… Nick: Anyway, Mai needs to take a break. I’ll call and ask her if she wants to go and see a film with us tomorrow. Phuc: Oh, I doubt it... She’s already fully booked for the weekend with her maths class, English class, judo class, and music lesson!
