I have difficulty understanding people who have disproportionate emotional reactions to unimportant situations. It probably stems from their mood. Some people react abnormally to certain situations because their hormones are not secreted enough. If they knew why they react abnormally, all the problems would disappear.
That's human nature. For many years, the system has tried to suppress human traits it deems unsuitable for social coexistence; I call it "control for passive slavery." You reminded me of a film called "Balance (2002)," where the system forced citizens to inject themselves with a serum to suppress feelings, a dystopian future where society is maintained in balance thanks to a drug that eliminates negative emotions.
Didn't A Brave New World have something similar?
It is funny. I learned recently that emotions are only meant to last about 90 seconds, but it is because we hold onto the thoughts of events and don't let go that they turn into moods.
