Why did my brother keep telling me he was going to “show me something” and now I am terrified?

My brother is 12. My sister is 16. My parents went to visit some family out of town for a couple days. It was supposed to be just me and the two kids at home, and everything was fine. Just your typical kids stuff. But then one day, I get home from school and I was messing around on the computer and I found this super creepy folder. It was password protected. <br><br>I immediately deleted the folder and told myself that I wouldn’t be messing around with it again. But then I got home and my brother was being weird. He was trying to get me to go up to his room. He was acting weird and excited. I asked him what was going on. He said that he was going to “show me something” but he kept putting it off. He kept asking me if I wanted to play this game or watch that movie first and then he would show me. I told him no. He was still being weird and kept asking me if I wanted to see it now.<br><br>Then I asked him what it was. He wouldn’t tell me. I kept saying no to playing games and watching movies, and he kept saying that he would show me after. Finally, one day, he decided to show me. I went up to his room and he was acting all excited. He opened the folder on the computer and I saw that he had changed the password. I was super confused. Then I saw that the folder was open and he was looking at something. I looked at the title and it said “creepy things”. I asked him what was going on and he started acting weird. I asked him what he had been doing and he just said he was going to delete it all.<br><br>He opened the folder again and this time I could see everything. I saw a bunch of random things. But then I saw some things that were really creepy. They were pictures of some stuff I didn’t want to see. I was super scared. I started crying and I asked him why he was doing this to me. He started acting all nervous and he told me that he had been watching a bunch of videos on YouTube that he found on his tablet. They were really disturbing and he started acting weird. He started acting like a creep. I got really scared and I started crying. He acted all sorry and he deleted all the stuff. But now I am terrified. I don’t want to be alone with my brother anymore.
