In my younger and more vulnerable years I was the chirpy kid who got to visit the flight deck of many an airplane. With a PPL in hand (pre-9/11) I was even allowed to sit up front for take-off, the majority of cruise, to the landing.
But after having a Captains' kid who was on the flight deck many moons ago, look up and reach for the T-Handles while asking his Dad what it did, I vowed to never allow any Jonny Public up front. That idea was only solidified later on when I was "voluntold" to work a ground display during an airshow. That's when I saw what an otherwise normally sane and rational person will do around an airplane, especially the cockpit.
I get it; it's cool for you. I was for me too. But far too many people want to play "grabby hands" and there is just too much in the cockpit not meant to be grabbed that way.
