LongHairGal, while I was a grade school child I would sometimes play outside on my block with kids from my side of the block and the ones on the opposite side of my street. Many times they would harass me (only one of them was raised by JW parents) and sometimes even try to start a fight with me, and I never knew why. I tried to get along with them. To the best I could determine it was either due to racism (I am a multiracial brown skinned person and they were all white) or because I tried to always be very good (to the best of my ability) and tried to avoid getting into fights and tried to avoid doing other things which the JW religion says is bad (such as playing with toy guns or celebrating pagan holidays or using 'foul' language).
My bedroom French windows had a latch on them to hold the windows shut but no actual lock. On many days I would have the windows open to let in cool breezes. There was a tall bush below the windows. One of the kids, a very bratty 'worldly' kid who caused troubles for me climbed up on the bush and reached out to come into the open windows! I closed the windows and he went away. Another time, but when the windows were closed, the troublesome kid not only climbed up the bush, but he also opened the windows and reached into (or nearly into) my bedroom while I was in my room! I thus pushed him away and closed the windows and then I never saw come up to my second story window again. But, one day either my Mickey Mouse watch (from my bedroom) or my sister's Minny Mouse watch was missing from the house (I forget which, maybe both happened) and I presume he stole it (or them).
One day on the grade school play ground 'worldly' kids took terms kicking my butt and when I would chase after one of them, one of them would kick me from behind. In high school a kid kept on jumping onto my back in gym. I would bend over and he would slide off my back and then get back on and the process would repeat. Why in the world did he act that way? Admittedly for a time even a Hispanic boy raised by JW parents caused me some problems, but thankfully in high school he didn't cause me any problems. In high school he was an A student.
A number of times I when I would open my high school locker (which had a built-in combination lock) I would find that some things (pencils?) were stolen from it and that some unwanted things had been put into it. I wondered how that could happen and who did it. Small things can be slid through slits on the door and the bottom and top of the door can possibly be bent open while the door it locked. Maybe the kid knew how to 'crack' the lock. I later bought a combination padlock and put it on the lock and started keeping my things in a hard to reach place of the lock (near the level of the locks) and that solved the problems. It wasn't until college that I no longer had any problems with 'worldly' people in school.
In one banking office job I had, about 10 years after I graduated from college/university, one non-JW young person (probably a non-Christian) started verbally harassing me (but carefully done in a way which probably couldn't get him in trouble, and he made himself a friend of the boss) multiple times a day after he learned I was a JW (I mentioned to him and the other two co-workers sitting close to me that I don't celebrate holidays and birthdays) - holidays and birthdays were celebrated in the workplace and thus my non-observance of such was noticeable. I think the guy was a non-Christian (and probably an atheist) because when I first met him he told me that he got a Christian woman to quit work and that I was her replacement (I and he were working through a temporary agency).
A number of other times I had problems with 'worldly' people, but hardly any problems with JWs or Kingdom Hall attending children of JWs. When in a group of JWs I always felt safe (including at district conventions) but not always when in a group of non-JWs.
