Common sense/critical thinking 101.
It is utterly baffling watching some people just bumble through life completely clueless.
I have lost track of the number of adults who have no clue how do their taxes. They either have their parents do them or they pay someone to do them for themselves. I consider myself basically financially retarded, but I still learned the bare minimum to be able to do my own goddamn taxes.
People don't know the bare minimum about their vehicles and it ends up costing them thousands.
People are oblivious to their surroundings and never prepared for anything even slightly.
People just do things without a single thought towards the potential consequences of their actions.
I love my gaming PC and 3d printer in the winter. Keeps my room toasty without me needing to run the heat much at all.
I hate those same things in the summer when I gotta have fans or AC just so I don't melt lol
