Gutrun and I have been in this room all day- Even the monks do not speak to us.

This is usually "bugger off" or something similar, but since the monks don't speak Morporkian, it doesn't matter much.

Only one monk, elderly and blind, speaks directly to the camera.

The monks do not always answer the phone and usually speak only Greek.

The younger monk spoke briefly into his wrist microphone, and waited for a reply.

Trappist monks generally speak only when necessary; thus idle talk is strongly discouraged.
