Sooner or later we all discover
that the important moments in life are not the advertised ones,
not the birthdays, the graduations, the weddings,
not the great goals achieved.
The real milestones are less prepossessing.
They come to the door of memory unannounced,
stray dogs that amble in,
sniff around a bit and simply never leave.
Our lives are measured by these.

- Susan B. Anthony
