Is AUTHOR wrong in the post ? POST : I’m in high school and have the ability to repair iPhones. Some kid gave me his phone and money to repair it, and when I told him it could be a week or so, he was okay with that since he had an extra phone. He handed me his money and his phone and that was that. 

I’ll admit that I forgot about it, and hadn’t fixed his phone. He came up to me asking for the phone and the money back, which I had no issue with. He then told me he had gone through my backpack to see if I still had it with me. 

This is where I got extremely upset and confronted him about going through my belongings without my permission. It nearly escalated to a fight when he refused to acknowledge that going through my stuff wasn’t okay and I wasn’t happy with it. 

AITA here? Everyone around me seems to think I’m in the wrong, but I don’t see where I was the issue in this situation. Is it wrong for me to be mad that people are going through my belongings?
