Bill grinned when he saw Louis head towards him, and had he been younger (or somewhere without his children) he would have considered joinging them in the pool. However seeing how his kids were here he figured standing by the sidelines was a better option.
"Hey," he said, watching Louis. "I am, it's a great house and a great party." Granted the house was much larger than anything he'd want to live in and also more elaborate. He didn't need to say that though. He was after all not going to live there, and if Jamie was happy then so was he.
