Good points by Bravo there.
I'm often surprised by fellow pilots who mighty be flying a leg with me who move the yoke around like they're driving a steamroller. One hand on the yoke and don't grip it like a vice; unless I'm landing/taking off/doing something brutal to the a/c I tend to fly with just my thumb and forefinger on the yoke.
I know it's a machine but try and have some empathy for the a/c; everything is done smoooothly.
