And many times every day, we trust others to do things like obey red lights and stop signs. One violation of those kinds of rules could end a life in nothing flat.
Just reminds us that life itself is precious and we should appreciate every day we are given...
You may trust people to stop at red lights but if I am at a light and it turns green I still always look for those gas smashing red light runners. It has saved me a few times from getting T- Boned.
