So for context My cousin (39M) lives in Saudi Arabia with his wife and daughter (9F). His wife recently passed away, and he came back to India with his daughter for the cremation and rituals. Soon after, he got very sick himself, hospitalized for 2 months on a ventilator. His home in India is in a different state from ours, so my mother and I went to visit him. We stayed at his house with his parents and his daughter, 9F During the visit, my other cousin (34F) came to visit him too with her daughter (5F) and her parents. So there were two kids in the house: 9F, who was grieving her mother and whose father was in the hospital, and 5F. 34F and family couldn't stay long because of her job and the kid's school, so they were going to leave before us On the afternoon they were supposed to leave, 9F refused to come for lunch multiple times because she was busy drawing. I eventually snatched her pen, which slightly ruined her drawing, and in response, she drew on my brand-new t-shirt. Now let me say this: the kid IS a bit of a brat, grieving or not. Naturally, I got angry and yelled at her. Later that day, we dropped 34F and her family at the airport. The house felt empty. I felt bad for yelling at 9F, so I sat with her a little, talked to her, and decided to buy her pizza to reconcile. The next day, 34F and her family found out I bought pizza for 9F the same day they left and got upset, accusing me of showing partiality or favouritism because I didn’t do anything like that for their daughter, 5F, while they were there. Apparently, it would have been fine if I had bought the pizza a few days later, but doing it the same day they left was an issue; apparently, 5F felt left out. They haven't been talking to us ever since. For context, I spent time playing with 5F while she was there, carried her around, and entertained her. 9F even mentioned that everyone loves 5F more than her. So, AITA for buying pizza for 9F immediately, 5F left? Also, AITA for yelling at 9F in the first place?
