i.e a kid who says everyone is fake(can be reasonable but you must accept people for their good), this kid is actually loathing for a good friendship/popularity. Say the kid lost friends, or was rejected throughout his life.

anther example is of a person; boy or girl saying she does not want nothing to do with relationships, will not ever fall in love but is secretly loathing for a romantic one to come her/his way? This boy/ girl has never have had a love one/romantic relationship.

people just say stuff subconsciously to cover up their insecurities? like for example one the boy/girl says this just to cover up having few friends, and example two the boy/girl says this to cover up her insecurity of never being in a relationship?

is this a reasonable idea? i am 17 senior in high school, this is just what i observe in individuals.
