The Jewish community has always been a tight knit group. If I want to know something about a Jewish guy, I can make two phone calls and learn his life story.
Turned out, the dude had lied to me. He was still in high school and had done some immature and violent things that made it clear that I needed to stay far away. So, I broke our date. I know it wasn't nice, but a girl has to think of her safety first.
A few years later, I was talking to a friend about Jewish Geography. I told him the story about my broken date, and he laughed hysterically because he knew the story from another angle. Turns out this high school kid had bragged about how he was coming to a party with a college girl. When he showed up alone, people asked where I was? When he told them I'd broken the date, they cheered.
I know he wasn't a nice guy, but I wish I hadn't put him through that. I hope he has forgiven me. It would have been better had I never met him.
