My mum made my sister and I party dresses, she was good at sewing and creating clothes from patterns which was nice, but for the fact that she always made us wear them even by Year 5 and 6 when all the other kids were wearing fashionable stuff. So shaming... But the worst thing was going to a relative's house for our holidays and mum and relative asked us if we wanted to go to a party. Of course we said yes we would. Mum produces these home made party dresses, which she had obviously known she'd need as we wouldn't normally bring them on a holiday...
So we arrived at some stranger's house in these deeply unfashionable party dresses, mum just goes away leaving us there. The hostess was clearly miffed that we were there and made us sit on the sofa in one room for a couple of hours, listening to the other kids playing party games in another room. The proper party kids all went for party food and the hostess said to us angrily, "Don't think you're getting any party food!" We had to sit there in the hostile atmosphere for all that time, listening to others having fun. 
For the life of me, I cannot think WHY we attended the party of people who were strangers to us - never even saw the birthday child, whoever they were - and why they were so angry with us, the two children that were utterly baffled at the way we were being treated. I still cannot fathom it to this day, it seems such a bizarre thing.
In a way I can forgive the hostess's annoyance, I would be too at having two strange children foisted on me (but I wouldn't show it to them), but she was really incredibly mean to us when we hadn't done anything wrong, it was all on the adults that had arranged this!
