What DovidM is saying is also at the root of certain behaviors that Yidden have that outsiders can’t stand. We act toward each other in a sort of sibling fashion and some people take it to the outside world, too. This is besides the cultural differences that we have.
This summer, after what I thought was a friendly chat with a shop owner, I realized that I was annoying him. When this situation repeated itself, I came to the conclusion that I was obviously getting too personal, something that would make sense with another Yid. It never occurred to me before, but I was forced to realize that I am part of a different culture and I still have more to learn about this country’s culture.
