Mr. Qu'an asks the teacher if he can have some water to drink on his birthday. The teacher says he can't because he's allergic to alcohol, but he'll give the girl some wine instead. The girl says she's not afraid of alcohol, and the teacher says she can have whatever she wants, but she'll have to drink from a glass of water instead of from a bottle of wine. Mr. Q'an says he'd like to have a toast to the whole class, but the girl is afraid of drinking too much, so he suggests that they have a drink of yogurt instead. When the girl sees that the yogurt is sour, she asks if it's made from vinegar, and Mr. Quean says yes, it is. He then asks the girl if she wants to eat grapes, and she says no, but that she'd tried it before, and it works. The tutor asks if the girl has been home yet, and he says she hasn't. He asks if she knows what time it is, and when she says it is , he says he knows.
