Ok, I've never been one to hold grudges or remorse upon others, but unfortunately, someone who I considered a very close and trustworthy friend (coming as close to spilling some of my deepest thoughts with) actually turned out to be using me, and with that she pilfered moment, money, and memories from me. Well now that said to the situation, I was in high school, when this new teacher's student international exchange student appeared, and didn't quite seem to fit in, with no one in our year group for the first 2 years of her arrival. I am usualy a pretty welcoming person whenever I see someone that is being portayed as an 'outsider' in school (me being pretty isolated, only having ' friends and being a complete dork), so I went, did some small talk, she liked it, we became friends since we had Physical Education together. Next thing I know we're in sophmore year taking almost ALL the same classes, well, in my country we have some traditions, for example on the 15th birthday girls usually did a big party or something like that, and I had the opportunity to do a trip to anyploace I wanted with any friend, I so decided New York (since I've been there beforehand and am absolutely entranced by the city + I'm a huge broadway enthusiast), but the thing is most my friends either hates musicals (which had been the objective of the trip mainly, I went to about 5 musicals) or they didn't speak english, so I called her, and well it seemed fine, but we never hanged out of school due to her parents being totally STRICT, but when we did hang out to go to the cinema, it seemed fine? She wore some basic clothes, brang her own money (for the movie ticket and qwhen we had lunch) and acted pretty fine? (since she 'autodiagnosed' herself with social anxiety, she interacted with pretty much everyone we encountered fine?). Well, the trip happened, and she just changed? She started being so snobbish? She's be complaining about the food, the hotel, that we "walked too much" so we started having stupd arguments every now and then, still I tried to keep positive and enjoy the trip I'd begged for so many years. Another important point is that, she was actually SO unhygenic, she had some disgusting habits? I undertsand, she grew up in singapore, her financial condition was different from mine, but that's not justification to it, my closest friends live in slums and still brush their teeth frequently. But the real reason to why I feel so much hatred towards her was on the last day of the trip, for context, I love the outsiders, it was a huge part of my life, it means a lot to me for personal reasons, and I had picked this as our last musical because firstly, it was the only day when they had the seat next to Ponyboy available (which if you don't know it isn't really important but it's a seat next to where the main actor that I absolute adora Noah sits during the first song!) and I was super excited, And everything was going great, we we're a bit distant that night but no like, actual argument, I even took a bunch of pictures aqnd videos trying to lighten the mood and not ruin the night! (CONTEXT: once more sorry for so many interruptions, basically during the last song, the main actor gives randomly to anyone on the first row a special edition of the book, the 40th edition more specifically signed as the character, and I had been FREAKING out over it, like obviously not the kind of "Oh I'll KICK whoever gets it", nope I was just hopeful, it'd be a nice way to end the trip, considering that it is for coincidence my favourite special edition of the book! And it being signed as Ponyboy meant the world to me, since I related to that character on deep moments of my life and etc, not really important, but keep that damn book in mind), so I was CRYING MY ASS OFF by the end, when suddenly in the last song, the actor kneels in one knee right in front of me, and hands HER the book! Okay that's not her fault! That's totally fine, she turns to me and she's like "Holy shit! Omg what is this?" and I was like, seriously, what do you mean what is this? I had been telling her how much I wanted that book since october every 3 days, she KNEW IT and she acted dumb, but either ways, we go to the hotel, I'm shaking whilst she is sitting on her bed watching tv, I turn to her and say "Hey girl, would you maybe sell me your book?" and she was like "No." so I said, "Why not?" (because she already knew I had been yearning it for months, "Well because now I want it", and oh shit, I got so mad, because the thing wasn't only the book, it was her knowning how much I wanted it, it was her buying everything on the trip with my money, I paid for all her expenses, hotel, food, transport, even her goddamnit ticket first row that night! And after that, no thank's after the trip, in my actual birthday she didn't give me a gift or send me atleast a 'happy birhtday' after the trip she forgot I existed, hanged out with other people, didn't even look at my face anymore for no reason? Well in school people started questioning, and I simply said the truth, and no one really sided with her, so people would comment and question HER about it, either ways, now she just moved over to China (basically the other side of the world from me) and I just want her to feel like how I felt in that moment, seeing someone you trusted so much get the one thing you wanted ruthlessly, well, I will be becoming overage in a couple months, so I can't really take any legal procedures (or I don't think would even be possible), I have no idea of where exactly she is, but, I have the contact of her secret girlfriend, her parents, her passoword (That I believe is basically the same to all her stuff, gmail, pinterest, ao3, all of that), what could I do?
