You have the choice to erase one incident from your past, as though it never happened. What would you erase and why?

I’ve written about this before in other posts that were concerned about the past. I wouldn’t change anything about my past and that includes this topic as well. If I started to edit my past then I would no longer be who I am and that would mean that on some level, my life is a sham. Since I can’t live like that, even having the potential to change anything about my past would invalidate my life and shame me deeply in regards to how I live my life today. So no, I own all of those incidents – the good and the bad and I hold them close and treasure them. They all make me who I am right now, how could I be any other way?
