BUSINESS LAW CAT QUESTION
Pixie is a single mother. She takes her daughter Rose (a two year old infant) to a local playground. While lighting a cigarette, Pixie starts talking with another young parent, Robert. Pixie is distracted by Robert's good looks and gritty charm. Meanwhile, Rose starts to wander over to the road. Robert notices a possible catastrophe and rushes out after Rose. Robert just manages to save Rose from being run over by Bob, who is driving a van within the speed limit and quite safely. However, Robert has too much forward momentum and collides with Bob's van. Robert is seriously injured. Bob skids off the road and crashes into some playground equipment. Luckily, no children are using the equipment. Laura, driving at speed behind Bob, sees the above-related events and puts her foot down hard on the brakes. Laura's car skids on an oil slick and crashes into a tree. Some distance behind the tree was Leo. Leo thought that Laura's car might hit him and he started running away screaming 'Oh Lord, don't take me now!' Leo has an underlying personality disorder and develops a paranoid fear of going out into the street. As a result, he loses his job and his livelihood. The accident involving Leo is witnessed by Barbie, Rose's grandmother, who is also at the park. Barbie suffers from a brief fright, but believes that she will be alright. However, she later develops post-traumatic stress disorder as a result of this event, combined with the news that Rose barely escaped a serious injury. She had not seen the incident involving Rose herself, because she had been busy setting out the picnic lunch.
