We recently came home from Taiwan to visit a relative, my uncle. He was nice, he took us out to eat all the time we were there, we slept in their flat, and we didn't have to pay a dime to him by the end of our visit. Basically all the very warm, welcoming, stuff. By the time we get home, there was a message to my dad from my aunt that my aunt's perfume which was like, 100 bucks was missing. There was no other visitor in the house. My dad didn't have his phone on during the flight so he didn't see it immediately. There was just us 4, me (F20), my sister (F19), and my parents. My parents couldn't have stolen it since they wore different perfumes, like far from the scent of the stolen one's. Plus, if my dad asked, my uncle would have given it to him if he can in a heartbeat. I can't wear any perfume since it really messes up my sinuses, so even if I did take it, it literally cant use it. I showed my bag to my parents, but my sister won't. She got really defensive. When asked why she won't, she can't answer. Only when her weed was brought up, that's when she spoke up, she said that mom knew what would be in there if she looked (more weed, she was caught multiple times but kept smoking. She also was the black sheep, so think rebellious shit), then immediately when out to her car, then drove off to do a "school project", according to my mom. I really have a strong, tugging suspicion that it was her. I know she somehow got it out of the house, and away from her bag, and into the car. Somewhere in it. Now, this wasn't a question of the item's value, but of trust. My uncle's family was quite rich, they owned a restaurant there so the price wasn't a problem, but the fact that she had the gall to do that after being treated so well was just painful even to me. The secondhand embarrassment was too strong so I told my uncle about that. He wasn't mad but I can tell he felt betrayed. I probably trusts her, hell, maybe even us all lesser. I won't even be surprised if they don't ask us to celebrate birthdays or New Year there. I feel like I should have just let my uncle think who did it, or review the cameras. There were cameras in the house, but none in or pointing at the powder room where the perfume was. I feel like I tarnished my dad's name, or something. But I know what my sister did was wrong, so it was just right that I tell him, right? I know I don't have proof but I know it was her, since everything points to her. So yeah. I really need insights. I feel like I'm in the wrong and at the right at the same time. I really want her to change, I have hope for her but I feel like this is too much, since my uncle did not deserve that, but then again, she's my sister. So yeah. I really need insights.
