I've never had a problem sitting completely motionless for hours at a time. I sit, mouth closed, in total silence waiting patiently for instructions, all the while careful never to let my attention drift towards ugly or seditious thoughts. Poised and attentive but never a distraction or burden. I'd be just as glad facing the wall or covered with a sack, whatever you think is best.
You're in charge for a reason. What that might be is certainly no concern of mine. If need be I can busy myself crossing and uncrossing my legs or shift my gaze to the ceiling.
Just make sure I get my sugars…and we all stay the good son.
