* Pollyanna's own actions: Pollyanna was known for her optimistic, sometimes reckless, nature. She was playing a game she called "the glad game," where she tried to find something good in every situation. She might have been less cautious than she should have been, and this contributed to the accident.
* The driver's actions: The driver of the carriage was going too fast, and his inattentiveness played a role.
* The town's environment: The road where Pollyanna was injured was poorly lit, making it more dangerous for pedestrians.
So, it was a combination of factors that led to Pollyanna's accident. It's not fair to blame any single person or thing entirely.
Would you like to explore any of these aspects further? Maybe discuss Pollyanna's character, the driver's responsibility, or the town's infrastructure?
