Mother: Lena, have you done your English exercises?
Lena: Yes, Mum, I have finished.
Mother: Come and have tea then.
Lena: May I help to put the cups on the table?
Mother: I have put them on the table, but you can bring the bread and butter from the kitchen.
(When Lena brings the bread and butter in, they sit down and have tea.)
Lena: May I go to the cinema when we have had tea? I have not seen the new film.
Mother: Haven’t you seen it? Well, you may go when you have finished your homework.
Lena: But I have done all my homework.
Mother: Well, you may go then.
Lena: Thank you, Mum.
