Hi so I’m M and today was my brothers confirmation at our church so most family members that we had came. Some of them couldn’t so after the confirmation, we went to a restaurant and ate something the whole time i was talking to my little cousin R ( who’s 8 ) i love her and she’s really sweet. I have no problems with her at all, after we ate we all went to our home and celebrated. My little Cousin and me went to my room and talked. After some time she told me that her friend has a hoverboard but never lets her drive with it. I said that I have one and told her if I would find it in the garage she could drive with it. Some time later my mom found the hoverboard and when we all were sitting outside table my mom asked me if I could let my cousin borrow my hoverboard because I had a posterior cruciate ligament tear and I couldn’t use it anyway. I said no because I got the hoverboard for my 11 birthday 3 years ago and it means much to me. I also was worried that my cousin would accidentally break it. I know it childish but my hoverboard just means much to me because I’ve got it from my parents. My mom got mad and said I was selfish for wanting to keep and not borrow it. I felt bad but still said no. Later when my cousin and aunt went to leave my mom tried to convince me to give it to them I still said no. When I went upstairs to get my phone I saw that the hoverboard was gone when I was back downstairs I got outside and saw that my brother tried to give it to my little cousin but her mother refused I was mad at my brother and my parents and said they have no right to decide over my stuff. My mom said " what’s the problem you’re not using it anyway and if it breaks, we can buy you a new one. " I know that but like it won’t be the same one that I’ve got for my 11 birthday I have memories with it and cling to them but also i have no problems with letting my cousin use it but I won’t borrow it to her so AITA?
