Well, most people just knocked. Somehow or another, it would be heard inside the temple. On the other hand, there was no real need for Celty to do that because Patchouli had gone out for a little bit and had just returned. What perfect timing!

"Oh, um, were you looking for me?" she said, walking over to Celty. "Sorry, I went out and should've left a note. I didn't think I'd be gone that long." That, and not a lot of people come around there anyway. Patchouli was very much the quiet sort, anyway.
