Piers once again wasn't sure if he was the one being greeted. However, due to the lack of people nearby, he figured it out pretty quickly. He looked back over at the blond man and gave a small smile before swimming over. Clearly, waving wasn't enough of a greeting but it wasn't a bad thing that Piers had to be more social.
When he got closer, he stopped a few feet from the other guy. "Hey there...enjoying the waves?"
