The source of disappointment

We live in an uncertain universe--no secret there. Life seems to be in a constant state of unceasing transformation. People and situations come and go from our lives. Expecting things to go in a certain way or others to behave how we think they should is setting ourselves up for disappointment. It isn't the person or the situation that has let us down but our clinging to the idea of how things "should" be. Life isn't compelled to play by our rules. It almost seems like life takes a special delight in questioning our assumptions and shattering our expectations. Ultimately, this is a beautiful thing. Life is a great teacher and by the time we breathe our last breath we'll likely have a PhD in letting go.
