There are many things in my life that have been extremely difficult. Some so hard I almost never moved beyond them. That said, however, I would never erase anything, as every single moment of my life has led up to me being the person I am right now. I would be erasing too much knowledge and strength if I got rid of any memories.
The last time I saw my mother, four days before she died. She was slumped in a wheel chair, totally unresponsive, the shell of the lovely and loving woman who so many decades ago told me her worst fear was winding up that very way. :(
When I was in the 6th grade and someone brought a magazine to school with redacted. It was the 1st time ever seeing redacted, and I surely thought it could not be real, but redacted.
