Example Input: Person1: When I was at school , I was quite good at track and field events . I was on the school team for the long jump , 100 and 200 meter sprints and the javelin .
Person2: Really ? I was quite good at the hurdles and the discus .
Person1: I wish that I were good at the discus , but I could rarely throw it in the right direction ! I was awful . With the hurdles , I could never jump over them !
Person2: I thought you were good at the high jump !
Person1: No , I was good at the long jump . I liked the sprints best .
Person2: Did you ever win any competitions ?
Person1: I was regional champion for the 100 and 200 meters . I usually did well in the dong jump competitions , but I couldn ' t compete with kids from other schools in the javelin . How about you ?
Person2: I came second and third a few times in the regional championships , but I never won . Did you ever take part in the national championship for the sprinting events ?
Person1: Yes , I did , but I didn ' t do very well . I made the final in both events , but came last . At least I made the final . I was very pleased with that .
