We were visiting some relatives in Sydney, but we return last night. ,F: Oh, I've wanted to go to Australia ever since I was little. Tell me what it was like. ,M: It was wonderful. We fed kangaroos, walkthrough rainforests and swam in the ocean. What was really great was when we took a train to Brisbane to see the Great Barrier Reef.
(A) F: I went to Australia when I was a child, but I didn't expect that the most impressive thing for you was to feed kangaroos.
