Parseltounge

As I sit in the Cathedral today, there are two people that have walked in. They are standing in the corners of the Cathedral whispering with each other. Their French language and hushed tones echoing through this place makes it sound like they are speaking in Parseltounge. The sounds bouncing off of the edges makes it sound like they are moving all around me through the walls. Is there a Basilisk Snake living in my favorite place? Just when I thought this Cathedral couldn’t get better.
