When I was a senior in high school, I picked up a stranger at the corner of a dirt road who was injured from an accident. It was also snowing, which was very rare where I grew up. By the time I dropped him off 15 min later, I regretted it. I had given him personal details about myself and my family and pointed out my own home along the way. He wouldn't tell me exactly where he lived, and he didn't want me to call the sherrif. (I did anyway.) I realized how many terrible mistakes I had made.
I think REALLY hard about helping people out. I have seen babies used as bait. IF I am armed, and IF I have help, (another armed person, which is most of the time I'm out,) I consider the circumstances.
