Dialogue:

W: Tom, I rang you yesterday, but you were out.

M: I'm sorry, Mary. But I came home quite late yesterday about half past nine in the evening. Jim and Betty invited me to go for a picnic.

W: Oh, how lovely, Tom! And did you like the picnic?

M: Yes, I liked it very much.

W: When did you leave, Tom?

M: Jim and Betty came in their car about ten o'clock in the morning, and we left soon afterwards.

W: And where did you go for the picnic?

M: We went to National Park.

W: Oh, it's lovely in National Park at this time of the year.

M: Yes, and the sun shone all day.

W: There's a river in National Park; did you have your lunch near the river?

M: Yes, we had lunch near the river. Then, after lunch, we went for a walk along the river. Then we climbed up to the top of a hill, and looked at the beautiful view.

W: What did you do then, Tom?

M: Well, we went back to the car, and we drove to another part of National Park, and we had afternoon tea there. Then we started to drive home.

W: Oh, you left early!
