Aibu to be angry about this - dd left out group/party

[Lago1]

So a bit of background, my daughter is a lovely, yet shy and reserved child, who has been dancing for a few years with a group of girls and has grown in confidence around them. One particular girl, she sees as a good friend and they share another hobby which they do weekly together. This morning at dancing she hears some of the others discussing a sleepover and asked in front of the mum if she can join and the mum says of course. She comes home excited and gets her things ready, then I received a text 15 minutes before I was due to drop her off saying I'm sorry dd doesn't want her to come. Now I know maybe she shouldn't have asked but it was nice to see her confidence and she would have not even considered that her friend didn't want her there and probably thought of it as an oversight. There were no excuses made, and not even any effort to try and protect her feelings in this all. I am so sad for her. Aibu to feel really pissed off?

One of the unfortunate things our kids have to learn is disappointment. I struggle with this for my daughter because she has ADHD and can be very socially awkward. If this happened to my daughter my gut reaction would be to get angry, but there's several things to consider. This could've been a gathering that had been planned for awhile. As a mom I run around like a mad woman trying to get things together. I had one party that I threw for my daughter's 9th that l could only have so many girls there (it was a painting party and the instructor was very specific about it). If a girl at school had invited herself, my kid said yes without asking me I would've had to uninvite the kid. Usually there is more to the story. Also she invited herself that day? Had my daughter done this I would've probably checked with the mom to see if it was okay because I know kids don't always follow what the parent had plans for. I know as an adult if someone invites themselves to something I hadn't intended them to come to or had wanted a smaller group it could be an extreme inconvenience and sometimes the person has to be told no. The mom could've also been in a big rush getting ready for the party. Texting is not the best in communicating tone or the entire story. I would just give the mom some grace. I have a feeling there's more to it. This could be a great lesson for your girl, even if it's hard as a parent to watch.

That's awful OP. Sorry your daughter has experienced this. I would be very pissed off too x
