I wasn't raised a JW, but became one in my early 20's. However, when I did move from the country of my birth to England I did have a whole set of built in friends there. It was pretty cool.My mother was telling me, "I don't know why you want to move here, you'll have no friends" and I told her don't worry about that.
Other advantages is that I'm not scared of approaching strangers, heck if you can go house to house and knock on someone's door and tell them about the Bible, .... :)
Man... I must have been crazy back then.
