Perry & Open
Perry wasn't so sure about this, but he'd been talked into going and decided to make the most of it. He'd watched as someone randomly dragged someone on the dance floor and decided to move back a safe distance. He couldn't help but keep a keen eye on everything that was going on. Hair changing colour, people were speaking gibberish. He had half a mind to find Weasley to ask if he'd done it, but he decided to let it be. No one was getting hurt, and a spot of fun didn't hurt anyone.
Instead, he stood with his arms crossed, leaning against a tree watching.
