Why can't our past lives just stay in the Past?

I was never going to win a golf  match. Not surprisingly, I dont much like to be reminded of those days. When someone recently found a photo of me when I  was younger I was mortified. Reliving embarrassing moments from my past can still be veruy uncomfortable Though I look back and laugh, the sencse of humiliation persists.
I would rather leave those episodes, so to speak in the past.
Still I rarely reflect on that particular life. It feels light years away from where I am today.
