Well, Stiles definitely felt stupid now. He'd interrupted something that was...sacred, maybe? And that was a crap thing to do, no matter where you happened to be from.
"Sorry," he said. "I thought..." He made a vague hand gesture. It was obvious enough what he'd thought and he wasn't doing himself any favors standing g here and awkwardly trying to explain himself.
"Um, so, the pool," he said, abruptly trying to change the subject. "Do they sell swim suits anywhere?"
He had about a billion questions he wanted to ask the guy about who he was and what he was doing, but it just didn't seem appropriate after he'd already interrupted his prayer time.
