I walked out along the bridge. The water (A9) ... past about forty metres below. I (A10)... a little nervous but now I felt sick. Perhaps doing a bungee jump had been a bad idea. 'If you (All) ... it, you'll regret it for the rest of your life,' said the instructor. 'In no more than two minutes you (A12) ... your first jump and you'll be a hero,' she continued. 'If you (A13) ... any doubts, you shouldn't have come up here,' said my friend Andrew, who was already putting his belt on. I watched Andrew disappear over the side of the bridge. I (A14)... worrying about the jump. Now I (A15) ... by the fear of failure. Not only were there people watching below, but Andrew (A16) ... his jump. 'They (A17) ... for you next,' said the instructor. Never have I felt such fear as when I stepped off the bridge, and seldom (A18) ... so happy when something was over. That was my first and last bungee jump.
