Exuberance is an intoxicant that affects people differently, just like booze. It is somewhat of an exuberant-inducing thing to take a drone to the air. People handle exuberance differently. Folks simply react, under-react or overreact to situations based upon their nature.That's why some folks CAN be fighter pilots while others would crap their flight pants.
I think the folks forgetting the gimbal clamp, etc., are just letting their over-exuberance override their thinking at the moment: just human nature for some people we share Earth with. That's why some folks can barely remember Mardi Gras and regret it while others are sharp as knives about how their trip went.
People are just different. And the more people you meet, the more you want a dog.
