The problem with expectation is that you are setting yourself up for disappointment. Whether you know or think you know the other person, it is inevitable that you can never truly know what a situation will bring. You might know someone well enough to expect certain behavior, but unfortunately, there is always unpredictability in what the other person will actually do. You can never truly know what is in the mind of another being. And of course, there is always the behavior that you know the person is capable of, but simply, inexplicably, they do not do.
Often times there are unforeseen factors that affect the outcome of a given expected action or reaction. Regrettably, no amount of preparation or expectation can account for them and fear is often the biggest obstacle – fear of rejection, fear of expectation, fear of truth. There are no rules or laws when it comes to expectation. It is human nature to have it. But it is also part of living to be disappointed by our expectations. For it is simply unavoidable to continue to have hope.
