I apologize, firstly, Han Lin, that I couldn't respond to your post earlier...as you'll see on my threads in this section, a lot's been going on, but still, I'm sorry I haven't been able to write anything until now!
Anyway, you asked if you should have done more. I'd have to agree with everyone and say 'no'. If I'm correct in my assumption, you are roughly the age of the friend you described. Now, that's not to say that 14 year-olds are powerless or are 'children', but at that age, there's only so much you CAN do, that is within your power. But really, in regards to getting someone to do the right thing (which is a theme in a few other threads in this section) NO ONE of ANY age can MAKE someone do the best thing for themselves...you told your friend what you thought and how you felt, you obviously care about her, and when you felt it necessary you reported the situation to a TRUSTED adult--a teacher.
I emphasize 'trusted' because the man you describe has abused his status so horribly is simply turns my stomach. To abuse authority in that way...to do something so incomprehensible...something so VERY against the law is simply stunning to me. HE was the adult in this situation, NOT you and NOT your friend (or the second girl he got involved with). I'm going to say what I said to Hermione Weasley to you, Han Lin, and please don't take me the wrong way. As I'm 25, and you are 14, in my book, you are a minor and still, by law and in my mind, NOT a legal adult...you are still a child. Not a ickle child, but a child. I don't mean that condescendingly...my point is that there are REASONS there are laws protecting children against these very acts...this man may not have forced your friend or her friend to do anything, but he abused his authority and he manipulated her and took shameless advantage of her youth and naiveity. That, to me, is sickening...and that's putting it mildly.
The dictionary defines a pedophile as:
Pedophile: An adult who is sexually attracted to a child or children.
I'd say the term fits, and not only is it horrible and disgusting, there's a reason there's a law against it, as I said. You did what you could, Han Lin. When I first posted here at BaO, I was upset because I tried to act as people's 'saviours'...I tried to 'save' people from their circumstances, situations, and oftentimes, themselves...not only is it a thankless job, but NO ONE can change a situation but the person making the choices.
You can talk to someone until you're blue in the face, but they have to see a reason to change for themselves, and that's one of the hardest things to do with someone you care about--to let go. Otherwise, you take on a pronblem that isn't yours that you have no real power over. You spoke to your friend, you supported her (gave her someone she could confide in), and when needed, you told a trusted adult (a teacher)...that was your best move and good for you for doing that...if her parents already knew, it's not your responsibility to save this girl from herself, but the person I REALLY blame is HIM...HE is an adult, and he should know better! And, he is, most likely breaking the law.
This man is sick...30 year-old men have NO business with young, who aren't even legal adults, girls. Never mistake that. He was the one who is wrong on so many counts, and it disturbs me that he's not just done this once, but twice! Still, don't hold yourself accountable for his perverse, sick, illegal behaviour, nor her childish, stubborn naiveity (which, by the way, adults have, too!)...she may have made some poor choices, but he preyed on her inexperience and youth, so she's very much a victim. I hope this man is punished...otherwise, why would this behaviour stop?? But even that isn't yours to do.
My best recommendation (and this would be entirely up to you) would be to (I don't know if you're out of school for the summer or not) is to talk to your parents about this. I know a lot of folks on here may disagree with me, but a man like that needs to be stopped, and the last thing you need to do is to try to stop him yourself and risk getting hurt, but what he is doing to these girls is WRONG and could turn violent at any time. I'm not kidding. Like I said, someone his age has NO business with young girls...I'm a true believer that if you have to hide what you're doing, most likely it's something you SHOULDN'T be doing.
I really hope this gets better, Han Lin, but as I said, please don't blame yourself or feel all your efforts were in vain...you did what you could and you are NOT accountable for some sicko's behaviour nor anyone's choices or actions but your own. I hope this (rather long!) post helps and makes you feel better.
Sincerely,
Lizzy
P.S.--I'd like to also mention as I worked for the YMCA at one time, we could have lost our job over ANY inappropriate (s*xual) contents by s*xual content, I mean inappropriate discussions or behaviour. with any of the kids we worked with...not just because we were adults and they were children (not matter if they consented or not!!!), but also because we were in a position of authority and that's a clear abuse of authority (which, in the workplace, between two adults would be 's*xual harrassment'). You just don't do that (get involved with minors as an adult, ESPECIALLY if you have authority over them [you're the adult in charge for a Scout Group, you're a teacher, you're a counselor, etc.]) for SO many reasons!!!
