My 70 year old mother received a letter from a law office asking her to provide her liability insurance information. A woman who attends a local senior center with my mother claims that she tripped over my mother's cane and broke her hip. It should be noted that the incident took place at the senior center; not in my mother's home. My mom is not sure if the woman tripped over her cane because she was getting up from the table that they were sitting at. My mom did apologize and offered to assist the woman with any bills. What should she do?
