Where does the time go?

How come some days take forever and other days pass by in a moment? I experienced both recently. My Love came to visit for a long weekend. It was gone in a flash. The next week after she left seemed to take forever to pass. I don't get it sometime. Yesterday we had a splendid wedding day and this coming week we will celebrate 43 years. Seems impossible. Yesterday our children were born, today they have children of their own. My days serving our military men and women and their families seem to be both consequential weeks and fly by in a moment. Touching someone which may have an effect upon the rest of their marriages or military careers seems so important. But no matter our experience of it, we best make the best of the moments we have today, because it will be yesterday much too soon. Dr. D.
