Eventually all suns will        their fuel, explode and then become cold and dark．Matter itself will disappear and the universe will become        for the rest of time．
This was the general drift of my thoughts as my wife and I      my eldest son as a freshman at college．That moment at the dorm is      at the kindergarten door, at the gates of summer camp, at every occasion of parting and      ．But it comes surprising, taking what you      most．
Our ancestors thought this parting should take place        ．In many societies adolescents were sent away to live with friends or relatives right after adolescence．This was supposed to       the conflicts that come from        teenagers and their parents very near．
Eighteen years is not enough．The days pass uncounted, until they        ．The adjustment is upsetting．My son is on the      side --- observant, thoughtful, a practitioner of companionable silence．I know this is hard on him as well．He will be homesick．Among the greatest        of college students is they won’t have a room at home to return to．
But with due respect to my son’s feelings, I have the              of parting．I know something he doesn’t --- incomprehensible to the young．He is experiencing the             that come with beginnings．His life is starting for real．I have begun the long letting go．Put another way: He has a wonderful future in which my part      decreases．
I’m sure my father realized it at a(n)      moment．And I certainly didn’t notice or understand．At first, he was a giant who held my hand and        my sky．Then a middle-aged man who paid my bills．Now, decades after his passing, a much-loved      ．But I can remember the last time I hugged him in his home, where I always had a room．I can only hope to leave my son the same．
My son, those days have been the greatest wonder and        of my life．And there will always be a        for you．
