Rubbish:----it's called Airmanship from Professional Aviators, cross checking and monitoring to keep us ALL safe.
It's also to helps make sure BOTH Pilots are in the same loop going the same direction the same way...... Don't you want the PM awake, watching and keeping you safe? He might just save your butt one day.....in fact it sounds like it will happen soon enough.
Just do it and stop being so precious...
