Sounds as though you had a great time and that you converted the counciller to be pro aviation if they wernt already.
It may sound a bit of a cop out but my first pax was my instructor. He asked to come up with me as as hes a nice guy and a friend there was no way I would have said no. The flight felt different to any of my training flights and I felt confident. If I remember the comment I got was I wish you had flown like this during training. I still have not taken up a non pilot as a passanger though I feel ready to in the PA38 but not the PA28.
