Cassidy & Open
Cassidy wasn't sure what to make of a party. It didn't seem to fit the mold. Granted he really wasn't going to complain. The food was good, the music was... okay- only every once in a while a song you could dance to came on, the rest were perfect for a cocktail party or something he'd imagine. That's probably why it was picked. After eating a bit and saying hi to a few people a song that had a dance-able beat (outside of a slow song) finally came on. He got up and started to bop a little in an emptyish space, clear of hitting anyone- completely unaffected by the fact he was dancing alone.
As the lyrics started Cas started to quietly sing along, the mood to dance strong with him. Without realizing it someone else within ear shot got up and started to dance too. For the briefest of second Cas thought that was cool he had inspired someone. They quickly realized what happened. Clasping his hand over his mouth, the singing ceased he watched as the other person slowly stopped dancing. "I'm so sorry." He said, reaching a hand out as he lowered it from his mouth. Apparently they hadn't actually felt like joining him, he'd sort of made it happen.
