What I didn't know from preious visits was that there is a modern day temple inside the outer wall. I wandered over and in a small shrine I found two young novise reciting scriptures. It was great and they were chanting different things out loud.
I took photos for ages and they were completely unbothered. Then a group of Japanese came along with a Khmer Tour Guide. He decided he knew best, told them to stop reciting at the same time and one should talk and the other should listen. They were clearly bothered by this group and looked away from their cameras and tried what the man had said.
As soon as they were gone, they went back to louding chanting at the same time and I went back to taking pics.
