Must admit as a new pilot I've never had anyone worrying about flying/having a loved one flying with me. I've even cured my daughter's phobia of flying. But then I'm a belt and braces type of guy, never use more than ten degrees of bank (and surprisingly you don't have to) when flying pax unless essential. Have you ever driven home with a pint of milk in the footwell of the car? You know how careful you have to be to stop it falling over, I always think of non aviator pax as pints of milk in the footwell. Every single person I've flown has always wanted another flight. Not down to my piloting skills I'm sure, it's just treating them like eggs and being thorough with everything.
