Mmmmm ...
A very difficult problem ..... years ago I got over this difficulty by having my 2 elder children hand write a letter to me .... it basically reminded me to "not take any silly chances when flying my helicopter, not to do anything stupid and to come home safely!" ...... it was signed by them (along with their then ages 6 & 5 yrs respectively).
I carried this letter with me in my wallet and whenever one of those moments arrived I told the recalcitrant that I was not authorised to comply with their request and showed them the letter. It was amazing the effect it had.
Cheers
BTW ..... An extremely good thread this one !
