Just when I was beginning to think it was safe to answer my door to unexpected callers here in Japan, I had a visitor that came bearing gifts. 
In actual fact, I'd met this well spoken young man before when I was living in Shingo; a village in which I stuck out like a sore thumb. Who else was he going to give these magazines printed entirely in English to?
I have this thing about always being nice to people. When telemarketers call I hear them out, then tell them I'm not interested. If someone needs a survey done, be it over the phone or in person, I'll do it if I have time. When people come to my door, I talk to them. In New Zealand, it got so bad that the Jehovahs and Mormons knew exactly when I'd be home and timed their visits accordingly.
I felt bad after having a heated philosophical debate with some Mormons once which left them in no doubt that I was not about to be converted. But guilty conscience be damned, when this Japanese Jehovah started asking extremely personal questions, I cut to the chase and told him straight out that I'll be happy to read his magazines, but I didn't want to talk about anything, so if he felt like popping round again, he can put them in my letter box.
The magazines aren't that bad at all. Along with the moral education, there are also interesting articles on history and geography with no religious bent at all.
My favorite articles in this swag however are "How can I say no to sex at school?" and "School friendships; how close is too close?"
As far as talking about sex goes, the general gist is that school conversations about sex are lewd and sordid and you should be aware of the unwholesome influence that "lovers of pleasure rather than lovers of God" will have on you, as these kids clearly have been brought up by bad parents in a family that exhibits "no natural affection". If you are hearing a conversation about "immoral sex" (so what exactly is moral sex?), then you should take your advice from the Bible: Proverbs 22:3 - shrewd is the one that has seen the calamity and proceeds to conceal himself. So hiding under your desk with your fingers in your ears will help? And watch out for hooking up! "You might hear your classmates talk about "hooking up" - a term that means having sex with no emotional strings attached. In some cases, kids hook up with casual acquaintances. In other cases they meet for sex with total strangers they have met online."
As for friendship at school, just check out what Paul has to say: 2 Corinthians 6:14 - Do not become unevenly yoked with unbelievers. If you do, this so called "friend" will either "induce you to get involved in wrong practices or spoil your useful habits". So how do you know who it's ok to be friends with? "You may get along well with a particular schoolmate. But ask yourself: 'is this person willing to do what Jesus commands? Does he or she want to learn about Jehovah, the one whom Jesus instructed us to worship?' As you talk with your classmates, the answer will become evident." Ooookay.
You can believe what you want to believe. Each to their own. Just don't come knocking on my door to tell me how to live my life.
