If you are a regular kind of person like me, then you start to forget the dates of memorable events, although the emotions linger. We remember the stories behind an object we received from an event but often find ourselves grappling for the exact date (or at least the year) of when it happened.
It would be nice to remember how long it has been since we had that memory.
So, the most practical way to do it, while we still can, is to write down the dates of momentous events in our lives. Do it as you please — electronic or hand-written.
And wouldn’t having at least a record becomes a story to tell?
