Who's fault? Uncle or kids?

Today was my youngest son's 3rd bday. My other two kids are 4 and 7.We didn't celebrate with the grandparents and uncle (my parents and brother) BC of covid. They had dropped off a present for him in the afternoon. After dinner we went to their place to drop off a portion of the cake and gave them some Halloween candy that we didn't hand out. We had forgotten to taken some pics with them in the afternoon so we wanted to do that as well. My brother wanted a hug from the the youngest. He was holding his arms out saying come here! Do you want a trick or treat? My son was hesitant to go to him.(They only see their uncle under 10 times a year during bdays and special holidays. The kids saw my parents and uncle in the afternoon when the presents were dropped off and at the end of the short (45 mins visit they warmed up enough to give my brother a hug. They are close to my parents since they come over daily to watch the kids them until September )My older two (4&7) were telling him don't do it! it's a trick! its a trick! They were laughing and being obnoxious. And holding the youngest back from going near my brother. Honestly I was clueless whether my brother just wanted a hug or had real treats for them. I told the other two to cut it out but they didn't so I just held the youngest up and my brother have him a kiss on the cheek and said here's your treat. My other two yelled "see it was a trick!!" And my brother then got the candy I gave them and gave my son one of the chocolate. And asked the other two if they wanted a treat. He already had the other two chocolate in hand to give to them. But the other two must have been disappointed and said it was a trick it was trick and ran back to the car. My brother went to them and said here's your treat. My 7 year old took the chocolate. And my 4 year old ran away. My brother asked her if she wanted it and she yelled no. He kneeled down to her level and said do you want your treat again? She yelled no again. she made an angry face at him and kept hitting his hand until the chocolate fell to the ground. At that point my brother was fed up and just got up and said the chocolate is on the ground somewhere to me and then said bye to the my husband and I.I was annoyed at my brother cuz he hyped it up as if he had sth for the kids. And angry at my 4 year old for hitting. The whole ride home in just lectured them about having manners. But I honestly feel like it's my brother's fault as well??!? via /r/Parenting https://ift.tt/3nIoezP
