> Now I stop to help anyone who's broken down on the side of the road

I have a certain amount of fear about doing this sort of thing. I am ashamed of that, too.

When I was in college (this was in a small city), I was walking at night by the library and I saw someone trip and fall in front of me. I asked if they were hurt and if I could help. He hobbled up and said yes, one leg was injured, but he just needed some help to get back to his car. I helped walk him four or five blocks, supporting his shoulder. In a darker bit of street, his friend tackled me to the ground and threatened to kill me with his gun. He took my wallet, ordered me not to stir from where he pushed me under a car, and they ran off. To be explicit here, the tripping and falling was fake.

The campus police took me to the student health services; my knee was banged and slightly scraped from the tackle. I related the story to the doctor and he said, "Well, you can't stop helping people." On the other hand, the cop just said, if anything like that ever happens, I didn't have to handle it myself, just call them, they were happy to come and assist anyone who might need help on campus.

I still help others when I can, but I am always cautious about my environment and assessing the circumstances
