Why waste your time and energy and risk offending someone when you get it wrong? Have no expectations for any person. When something positive happens, you will be pleasantly surprised. And, when something negative happens, you will not be shocked, sad, or angry.
If you say "have no expectations for any person" and so doing, when something negative happens, one won't be shocked, sad or angry, then I will say you are indirectly implying that one should expect something negative from everyone and when something positive happens, someone can be pleasantly surprised. 😱😱😱
