I've been on the Birthright Israel trip. It was the best vacation I ever went on in my entire life, even though it was a regular NT-oriented trip. I didn't make friends in the group, but the people were cool and easygoing, and not a single person bullied me the whole time. (In fact, when the group went to the Western Wall upon arrival to Israel, I actually asked God to keep people from bullying me; I guess he heard me.) Anyway, I handled the trip very well; I even went out clubbing one time, and felt right at home on the crowded streets of Tel Aviv. And in a way, "right at home" could very well be taken literally.
