Its hard for me to get truly "bored" because when I don't have anything in my immediate presence I sort of blank out and do weird shit in my head. I eventually latch onto something and formulate some ideas and then want to test them.
For example, I was sitting there listening to someone tell me a fascinating story about fishing (what lures to use, best bait for this or that fish, ways to reel them in, cleaning the fish) and quickly got bored after it devolved into rambling about some jerk with a beer. Then I blanked out and imagined an auto fishing machine and an elaborate way in which it would catch a fish and reel it in to a main cage. Inside the main cage there would be a trigger mechanism that would only activate if the head were to go into it then sort of like an intricate thing to instantly grab the fish and a precision cutting to get the fish into portions to be consumed. Then the meat would be flipped into a 3rd storage area and sit until collection. I was considering all the different factors that could go wrong with that and was endlessly entertained the whole rest of the night. It sucked because that was a time when I was trying to be social and be around people. The design kept changing and shifting from as low tech as possible to more high tech then I began to take in consideration seasonal differences, sorting so you only had fish of a specific size or type, and a 100 other things (which mostly just made me aware of knowledge gaps) I was imaging auto fishers setup all along frozen coastlines where the meat would about be stored indefinitely. Then imagined animals trying to get to the meat and the process repeated as I imagined an auto tanning setup so you could have animal hides, LOL. Dunno about realistic applications but it was a lot of fun.
I also can't get bored at night. I took a piss outside last night (had no choice and sometimes I like to do it anyway to remind myself I'm an animal) and somewhere in the process I sort of got lost because there was a light breeze and fireflies. I could hear almost a gentle sort of music between some crickets and frogs and I imagined what they might be doing and had some image over two male toads battling over a female (this quickly got ridiculous, complete with armor and swords and laser beams). I imagined some overly dramatic scene with a full dialogue but then if you were just happen upon them it would just be two male frogs bumping each other. Then there was the sky in general. How can anyone be bored when looking at stars? I completely lost track of time or what I was even doing. Someone came to look for me and I had to make up some stupid excuse as to why I was still out there. I figured they wouldn't understand that I had been sitting over a puddle of my own piss for 30 minutes because I got distracted by battle toads, alien worlds, the state of my own world, etc.
*Also I will have an impulsive response to things but usually won't act on them unless I'm very stressed.
