Can I just say what a stupid thing that is to say in general?
As had happened the last couple times, I reminded them that I was an atheist and there was no one to pray too. The best I could hope for was to walk carefully and try not to get hit by a car. I'd fallen on the ice on campus a couple days before and told the boss to take it to HR that I was concerned that I broken my kneecap for a time, and since I didn't have insurance, my only alternative would have been to sue the school.
I mean, if there isn't anything to be done about a bad situation, you don't really need to fill in the space with nonsense. Sometimes the uncomfortable silence is a better message.
