#Person2#: A driver died instantly. The other one was badly hurt. A poor boy called Peter was killed in the accident too.
#Person1#: What a terrible accident! Who should be responsible for this traffic accident?
#Person2#: I think both. They drove too fast. What's worse, one of them was drunk.
#Person1#: Why do some guys like to drive so fast when they are drunk?
#Person2#: I don't understand. Maybe they feel they are okay and driving fast seems very cool.
