"would you like someone to watch over you while you fly?"
or the reverse "nobody should know what or where or how I intend to fly and anybody curious about that is infringing upon my privacy"
That feeling is quite alive among a part of the Belgian microlight fliers. I once heard a story of a long planned group flight abroad, so that in a strictly legal sense filing a flight plan was required. Yet when one participant actually did so, another promptly quit the party, saying that he wouldn't fly in the company of people who didn't respect the proper microlight spirit.
I'm sure that same feeling exists elsewhere too; though it seems to me it is on the recline.
