My dad is 70 at the beginning of next year and we've said that we would have a summer party at our house and invite all the family. For his actual birthday my dad said to my mum that he would love to go out for a meal with just me and my DB and mum, no partners, no kids, just the four of us. I said lovely, my DH is fine, my DB says, "No".
He thinks it is wrong and that he and his DW come as a package, he ended up shouting at my mum on the phone when she was trying to encourage him to change his mind.
I talked to my mum yesterday and she is very upset and disappointed that my DB feels this way and also that he shouted at her. So we decided that we would go out for the meal anyway, just the three of us.
So I was looking for some opinions on whether it is an unreasonable request to ask that just this once, we go out together as a family unit without partners?? What would you say to your DB?
