We are all waiting on something. It could be an event, a person, or a feeling. Sometimes waiting is hoping - either for the future to arrive or for the past to come back. In many cases, waiting is all that is available in the moment - a wait that does not stop the moment at hand from passing swiftly by.
A simple thought, to be sure, and a good reminder to enjoy the moment. Because if a moment is all we have, waiting is a poor substitute for what really happens around us.
