Sisters unreasonable with ex xmas

[Tilly352019]

Hiya all just had an argument with my sister over Xmas with her ex. AIBU .So my sister and her partner split up over a year ago and have a DD who is 5, now my sister is demanding the ex to bring all her presents to her house so they are all together but he wants to leave them at his so he can open them there, she is refusing this idea and saying her DD is not going anywhere xmas day she is staying at hers. I bought up that her DD can have two lots of presents and what’s the issue, to which she asked me and my twin sons to leave if I’m taking sides??

She's being unreasonable but it's none of your business. Up to them to sort it out

Yes I no it’s not my business and it’s theirs, I just feel sorry for my niece that’s all.

What does she mean "leave?" Were you visiting her for the afternoon? She's being a bit unreasonable but it's not worth falling out over, is it? Not really your beeswax... I don't suppose it bothers you one way or another. Maybe she feels you're being disloyal?

YANBU
Your suggestion sounds sensible but as she has a bee in her bonnet sense won’t matter to her .

She’s my sister and il always take her side, she was stressing to me about it all and I just said what’s the problem with her having two lots of presents, I was visiting for the afternoon and when she asked me to leave I did calm her down.. I was just shocked at her reaction she was asking my advice and I was just trying to get her to chill out.

Ah the error here is she wasn't wanting your advice....but your support of her behaviour and affirmation that she is being reasonable and acceptable. It's likely she deep down knows that it is not not cool to make those demands, so you hit a nerve confirming her worst fears by opening the door with your question. Maybe she needs a bit more time to think it over.
