It may be weird, but I am really hesitant when in someone else's airplane and they say "you want to fly her?"

It's not that I'm afraid to bend their bird or be lack-luster as a pilot, I just don't like stepping into an unfamiliar aircraft and grabbing the controls.

Then again, when I'm PIC in a two seater, I don't offer the controls to the pilot rated passenger, so I guess the books are square on that.

Maybe if I were a regular in someone else's aircraft and was familiar with everything I'd think differently, but on the "one off" flight I'm happy just to follow along on the controls or enjoy the flight.

Am I alone in this?
