I got it from my college roommate and he got it from me. When someone makes an agreement with me I expect them to live up to it. Even when I was 18 and even younger. Sometimes I was disappointed but I still had an expectation that they would honor the agreement and I don't think that was unreasonable.
No one ever broke an agreement with me with the intention of humiliating me. I think it is even more reasonable to expect that that not happen.
“Sometimes I was disappointed but I still had an expectation that they would honor the agreement and I don’t think that was unreasonable.”
Well, I am glad you were only disappointed “sometimes”.
