Im sorta in the same situation. One of my so called "friends" borrowed my ring and she still hasnt given it back :( ive just learned to let it go, because usually I get super frustrated. I try to stay away from her.
If I where you I would talk to her mom or something, then stay away from her!
HOney, you just encountered a " gold digger", she used you and now she won't pay you back. Don't even bother because you're not going to get that money back, she manipulated you and got your money and now you're asking for it back, so don't even bother with it. Take it as a lesson, be careful who you lend money to because people will manipulate you or sweet talk you to get money from you, its happen to be sooooooooooooooo many times, from having a heart and being caring.
Just never give your money out again, if someone wants to buy something make sure they have their own money, to buy whatever they want. You're not responsible for them, only give it to people who you trust. Trial and Error!
What I mean is you can buy something for someone, but make sure it isn't expensive, when you do buy it for them.. and you don't get it back, take it as a good cause and that they're selfish and you're not. However, what goes around comes around! IF she doesn't pay you back, eventually someone will use her and take her money and not pay her back.
Live and Learn! Always be true to yourself, know that you're very sweet for what you did for her, you did a good deed. Eventually that good deed that you did for her, will eventually be a good deed that will back fire on you, but something way better then just money, maybe even more money given to you for being a good person, ( good Karma) As for her, people will eventually see that she's a gold digger and no one will want to hang out with her because she uses people, no will will trust her, she will have a bad reputation and she's going to have to learn the hard way that money deserves to be earn and not taken for granted.
Once, she's taken for granted she will know what it feels like. You can't change her, but she's spoiled. She needs to learn about the actions that she makes and try to better herself from not making those actions again.
I personally wouldn't hang out with her again, find better friends who won't take advantage of you because of having a heart, heartless people end up alone. I'm going to tell you this flat out, they were brought up to take and take and never give back, when they want a favor or want something they're going to realize that no one wants to be around them and do a deed for them. She was never your friend, because if she cared that much about your feelings or whatever she would've respected you and gave you that money back.
Just sit back and watch her fall off her horse, because its going to back fire eventually.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
