So for context. Me a (13M) and my sister a (18F). I know that this title is really weird but i need to know if I'm the ass hole in this situation. Okay now for the story. Me and my other brother a (11M) where playing in the basement of are house, (btw sorry for any typo's or misspelled words i have a learning disability and I'm not the best at tipping lol) so back to the story. My mom was making dinner in the kitchen when my mom told me to my mom said for me, "Go tell your sister that dinner's ready" I said. "okay" And i went to go tell her, I knocked on the door once when my sister yelled " to go away " but i was not going to give up that easy, so i tried to talk (btw the door is still closed) and she yells again, but this time it wasn't word's just screaming. So i said hell no. (in my head) And sat down at the table and started to eat. After i was done i when back down to the basement. 10 Min after that my mom is screaming at me to come here, i go upstairs my mom dad a sister all three on the couch my mom and dad are both staring daggers at me. Deer readers do you want to what my sister was doing in her room? Well she was playing on her pc, she screamed at me because she was playing Minecraft. my mom and dad both told me that i had to apologize for not telling my sister dinner was ready, i said that "i tried to but but she screamed at me to leave" my sister lied and said that "she never screamed" i scoffed and said "she's lying" but my mom and dad said that I'm banned from eating food intel i apologize for what i said. So reddit AITAH for not telling my sister dinner was ready?
