He was forced to have this celebration because giants of Order are set in their ways. He doesn't mind that. They can have a celebration if they want to have a celebration. But they forced him to attend. That's already bad enough. Then they took the one thing that could have made the event pleasant for him.

Then he will see how much fun they are having with it.
