This what happens when you are weak mentally and emotionally, have no character and no confidence whatsoever, with zero social skills. Being intellectually smart is irrelevant in this world if you don't have social skills, although I don't consider myself intelligent, as intelligence implies adaptability, and I am far from adaptable.

All my life I have been afraid of social interactions and I avoided it whenever I could. Even when I go to grocery stores, the cashiers don't seem to be happy dealing with me, just based on my face expressions and general look as I barely do or say anything. They say "hi how are you? and have a good day" to the person in front of me, but when it's my turn, they don't say anything. No hi, and nothing. I probably communicate non-friendly non verbal signals. That's why I prefer to go to stores where they have self check-out machines, because I don't have to deal with people.
