I should probably start by saying I'm not actually his uncle but my cousin and I were raised together like siblings so he knows me as his uncle. So I 27m was visiting my cousin 22f and my nephew 5m for the weekend and while she had to go to work I would watch him. I saw a local theater was showing the first Shrek movie and asked if he wanted to watch it. He said yes so I called up my cousin and got her permission to take him to the theater. We went and he had a blast I even splurged a little and got him an icy and his own thing of popcorn. When I got back to my cousin's place I was met by my very angry aunt. She was livid that I took him out without telling her. She said "I was planning on taking him to the zoo you should have told me you were doing something so I didn't waste my time driving out here" I told her I let my cousin know and that I wasn't even aware she was in town. This made her even more angry "it shouldn't matter I'm his grandma and I should be first considered when it comes down to taking him places" I apologized but said it's not that big of a deal it's still early and she could take him to the zoo now. By this time my cousin had gotten home and joined in. I'll call my aunt K and my cousin E to help from here out. K "E I told you I was coming to pick him up and OP was out at the movies" E " ya I know that's my bad I forgot you talked to me when he asked." Me " seriously it's not that big of a deal you can take him now and have more then enough time before dinner." I got a call and had to step away so I'm not sure what happened in-between but when I came back E was now on K's side. E " OP she's his grandma and has priority over you, you should have talked to her first so this confusion wouldn't have happened" K " ya anyway you took him to Shrek you could have just watched it here and when I got here I could have just taken him" I tried my best to explain that I just thought it would be fun and that he had a great time but K wasn't having it. K "OP you're not his uncle this whole thing is just ridiculous I don't even understand why you would take him out in the first place" I got mad and let into her " K I've been in his life longer then you and was the only member of the family who even showed up when E was having him. I have just as much say in what he does as you do I asked and E said it was ok to take him to the movies. I might not be his actual uncle but that's neither here nor there because I still show up when he and E need something. I won't be made to feel bad for taking him to have fun and see a movie he likes." Before she could say anything I left. Over the next few hours I got several texts from both of them telling me I was being childish and was a bad influence on my nephew. It ultimately ended with a text saying I wasn't aloud to be alone with him for the foreseeable future. So tell me reddit AITAH?
