Brother and sister in law informed everyone yesterday that they got tickets to Glastonbury this year, and they will be going for the full duration. Which means they are going to miss out on not only their daughters 15th birthday which is on the Saturday of the festival, but also my parents 50th wedding anniversary party, which has been arranged since last year that we will be hosting a party for them on the Sunday. Their two eldest children who are 20 and 23 also bagged tickets along with their mates, so they also won't be there.
I told them all that it's not fair or responsible for them to have booked tickets, they all obviously knew it was their daughters/sisters birthday and my parents wedding anniversary. The whole weekend was going to be a huge family get together, however not anymore. My eldest niece even tried to argue with me about it, saying how it's the 50th anniversary, always been on their bucket list etc. I don't care, they are missing important family dates.
They have said they are celebrating their daughters birthday the weekend prior and that they are even going to attempt to get a ticket in the resale for her, although it will be tough to get, however if they do, they'll then take their youngest who is 12, and can get in for free. So potentially the whole family will be absent.
I'm furious. They have ruined the party already, they should of never of even thought about getting tickets, it's so unfair for my parents.
I'm tempted to message my brother, and beg him to not go, my mum is quite upset that he won't be at the party. Aibu to be so angry at them all?
