Relax
My examiner for my skills tests told me to regard him as though he was a savvy neighbour that I had taken up for a flight.Have a bit of light conversation,ask him to hold your chart etc,make it interesting for him also.During my training,I did regard him as some sort of sky god but I have subsequently always enjoyed flying with him.His attitude is although flying is a serious business try to have some fun as well.
