Sin/Vi
Me neither. If the Order can plant bombs at a ball, I don't know why they can't just focus their attention on evacuating muggleborns from Diagon Alley and do something useful that aligns with their cause.
I'm just really glad it was an event for adults. If it had been a child-friendly function, some pre-Hogwarts kid who doesn't even have a wand yet could have been hurt instead. Not that it makes anyone else's injuries okay, but. I think I'd take it even worse if people were gloating over a child getting hurt.
