A Forgotten Memory

In Byron's collection, marks a folded leaf
With the tally of a game I once played.
Whomever the people were, I know not
Only their first initials. The game, even
I know not, for there could be a couple
Which the scores would represent.
Was it Dad and Victoria? 
Was it Dad and Valerie? 
What even was the game?
Were it even someone I now know;
Maybe a forgotten person from my past
I met once, and never would meet again.
No game comes to mind, it is completely blank.
Eerie is this feeling, that some part of my life
Vanished, and how much of my life is documented
And I know not who, or what, or when, or how?
