I give the respect to professional pilots to not be "that guy" just cuz I fly a put put plane and this is their day job!
I like showing interested passengers, both young and old, around the cockpit. COVID may make that a bit more complicated, but during normal times, come on up when you board.
There are times when we're busy and wouldn't have much time to interact but we usually do. My (personal) goal is to have all of my preflight and setup done at least 20 minutes before departure so that there is time to handle anything unexpected that might turn up (and drink coffee, of course). As long as I'm on-track time-wise, I'm happy to let visitors sit in my seat, push a few buttons, and ask any questions.
I also like audio/video equipment. Was involved with our campus radio station in college and work part time at a local AM/FM station. I like the equipment and the setup. I like to see how it all works together. Learning what balanced audio was, and what it does/allows, is still a milestone event from my youth.
These days, I find myself watching YouTube videos of people showing how they setup their network racks.
Once YouTube channel that I really liked, but has now gone silent, is
www.youtube.com/FiberNinja. He documented a number of jobs where he went in to a business and rebuilt their network set. He took some complete disasters and turned them into nice neat, clean, functioning, and maintainable setups. Sounds really boring, right? Somehow, though, I couldn't stop watching.
