1) People who try to belittle me or my intelligence
2) People who suck at their job. Everyone can have a bad day. But if you don't have the patience or social skills, to deal with the public. (Pick a different occupation.) Don't treat me as an inconvenience, ahole.
3) Those lacking basic manners.
Hold the elevator when you see me approaching.
Open the door if my hands are preoccupied.
Let me ahead of you in the checkout if I have 2 items but your shopping cart is full.
Personally for me, it's offensive af for people to look at you and not care. Self absorbed
I find that mental stimulation can be just as, if not sometimes more so, fulfilling and pleasurable than physical stimulation. Feelings of pleasure from physical stimulation is all just a form of mental stimulation anyway, its all happening inside you. So feed your mental stimulation constantly so it can grow!
