Final answer:
Jordan tells Nick she dislikes careless people and appreciates him for not being one, indicating she sees him as considerate and responsible.
Step-by-step explanation:
When Jordan tells Nick, "I hate careless people. That's why I like you," she expresses contempt for those who are inconsiderate and irresponsible. Her statement implies that she perceives Nick as someone who is thoughtful and meticulous, which is why she is drawn to him. In this context, 'careless' refers to a disregard for others and one's actions, while liking someone for the opposite reason suggests the person is seen as considerate and responsible.
