Harper entered the celebration warily. She tried to keep to herself, staying against the edge of the inside, her hands clasped together. She fidgeted and seemed to keep hiccoughing. She couldn't keep the giggles down, they were just...BOILING OVER.

"Hmm...hmhmhmhmmhehehehehehe..." she giggled quietly, trying to keep her face straight. There was nothing that was even remotely funny to her - Ravenclaw had won, and she didn't have any sweets in her hands yet, so really there was no reason to giggle. But yet she continued, pleading with herself to stop.

"Teeeheee...." she bit her lip hard and pinched herself, in hopes that it would bring her out of her giggle-trance. No use.

Giggle giggle.

This was a celebration. There was absolutely no excuse for laughter.

This just brought on a series of more giggles as she tried to cover her mouth with her hands.
