AITAH for laughing at my father's funeral?
Hi reddit, I apologize for the infodump, but it's needed for the story. My dad has always had incomprehensible amounts of money, but he made sure to raise us as humble as possible, in part because he was extremely frugal. That changed after his divorce and remarriage to my stepmom, who brought two boys with her from a previous marriage. My dad loved having boys after raising three daughters, so we were excited for him to go on ski trips and soccer games with them. However, the atmosphere was always off. The boys seemed to think of our dad as a walking wallet and my stepmom never treated us with much warmth. When my dad got sick, it took her no time to put him in hospice and since she had legally every right to do so, we could do nothing. Quicky after, the family accountant told us she was giving large sums of money to her sons, but us three agreed that, though it sucked, we didn’t need the money, so we let them. We did try to push back about her neglect of our dad, but even when he was on his death bed, only her and her sons were there. She only informed us once it was too late to say goodbye.
The funeral was fully in our stepmom's hands. We fought to have any hand in it, and all we managed was picking a song. My stepbrothers both got numeral grand moments and long speeches. It felt like it was meant to make us look like we abandoned him and that his new family cared much more. Even this we accepted, until one stepbrother's speech. He didn't talk about my father’s jokes or the way he loved reciting old timey nursery rhymes like they were great words of wisdom. Instead he told stories. One about how my father once bought out a resort for the boys and their wives and kids, one about how he treated an entire restaurant and the last one, which was about my father paying for his wedding and "not allowing him to even consider paying for anything". Now me and my sisters know that isn’t true. He had given the three of us a dowry and wanted to put that same amount into my stepbrothers' weddings, but this brother kept whining to his mom to keep pushing the budget up.
So when my stepbro said this, I burst out laughing. Not a quiet chuckle, but a full witch's cackle. He stopped to stare at me, as did other people. My sister quickly planted her elbow in my ribs, but the damage was already done. Since then, my dad’s side of the family has completely shut me out. None of them talked to me at the reception and my stepmom and brothers have blocked me on everything. My sisters are telling me I should apologize to not lose my dad’s side of the family, but grovelling to these people is not something I want to do unless I really am in the wrong, and I don’t think I am. I know me and my sisters never shared the details of our step families’ evil with the rest of the family, but I’d rather explain it to them than apologize. But my sisters think that will just blow everything up. So, AITAH for laughing at my dad’s funeral and refusing to apologize?
