Having walked around Brooklyn, I know that religious Jews never pay attention to others, and won't even reply to a friendly "hello" on the street. However, last year around this time it was even worse. I said "Hey, man" to someone and he started to boo! He even pulled out something that looked like a really fake gun and started waving it!
What did I do wrong that was so offenseful? How can I deal with religious Jews in a way that they will respond to??
