Keep Your Guard Up
It’s possible that the father’s decision to bring his son to the office with him, even though he didn’t want to, saved his son’s life. If he had done what his father did, the results would have been terrible for him and his family. He might still be alive if he had stopped to get a cup of coffee on the way to where the accident happened.
Still, if you complain, nothing good will come of it. Even if the car is a total loss, it shouldn’t be a big deal because replacement parts are easy to find. His good behavior throughout the day is shown by the fact that he took care of business at the office and paid his share of the bill in full. It’s not clear if he mailed or gave them the money in person, but given the circumstances of the accident and the lack of information, I think they were sympathetic.
