Disasters are unavoidable. Advise your friend not to take it too seriously. It's just a minor car accident. As long as the body is not injured, it's fine. But no matter what, no one wants such a thing to happen, so it's inevitable that there will be some psychological shadows. Please enlighten him more.
It's also very distressing that the car is damaged. You can accompany him to repair the car and give him a small gift. It is recommended to use a small ornament that can be placed in the car. You can give him a lucky star to put in the car to avoid disasters.
You can also choose a small gift for him, a real doll, which can be made into a bobblehead doll. Putting it in the car is enough to remind him to pay attention to traffic safety.
A little bear doll is a very cute doll. It can also be placed in the car to relieve his mood.
There are many other gifts. You can go and have a look. I hope your friend gets better soon. I hope it helps you.
