20 long years, each one shorter than the last
You stood by me all the time.
And yet, for reasons I never knew, the distance from me to you grew further, though you never lost sight of me.

On the 19th year, I turned around, and I saw you once more.
Lost, directionless, confused.
I thought back to those long summer days in our backyards, where we played.
And I realized I couldn't remember.
I don't know who I was back then. I don't know who you were.
I can't figure out who you are now. You don't seem to know either.
But I know who I want to be, and with a heavy heart, I must leave you behind.

Your mind has long gone, your heart has lost its way. Should I blame myself? Could I have saved you all those years ago?

20 long years.
And though it pains me to give up on you after all this time, I know deep down that I have no other option. Farewell, lifelong friend.
