By the time we reach our 50s, most of us have experienced a moment when, for the first time, we truly confront our mortality, a moment when it suddenly and forcefully comes home to us that we ourselves personally actually are going to die — as in: be dead — someday. This revelation can be produced under varied circumstances: It happens for one person upon the death of a friend, a contemporary; for another while he or she reads "Four Quartets":
We are born with the dead:
See, they return, and bring us with them.
The moment of the rose and the moment of the yew-tree
Are of equal duration.
("Little Gidding" ll 230-3)
In my case, the moment of terrible certainty about my own death came not as a moment of the rose or a moment of the yew-tree but rather as the moment of the box of staples.
I was rummaging in a desk drawer searching for the always elusive roll of "forever" stamps and for some reason I paused to read what was written on a box of staples I saw there: "Swingline standard staples / fits all standard staplers / 5,000 staples."
