Alice:  Hi, Jerry, I heard you have fun with Peggy in Merry Park yesterday.

Jerry: Yes. We had a great time there. Why didn't you come with us? We got there by bus in

         only ten minutes.

Alice: I know, but the ticket is more expensive on the weekend. Also, I've been there many times

        since it opened five years ago. Did you try the Dandelion Seat there? It's so popular that people 

        have to wait for over an hour to get a ride.

Jerry: You mean those flower-like umbrellas that fly high in the sky?

         I'd feel like I could fall down any time.

Alice: Maybe you would like it more at night. It's wonderful to see the beautiful lights below your feet.

Jerry: Well… I'm afraid of high places.

Alice: Oh, I see. That's too bad.
