Your kind response to this terrible email is amazing. I am sure my FIRST response would not have been kind at all, but by pausing and considering for the day on the "how and why" of his email, you came to the very best conclusion. I am awestruck by how you were able to handle this experience. I've had only one unkind response in my two years on MEDIUM, and I chose to not react at all. I feel I was guilty of being unkind once, when I was a new writer here, and I still regret that response. Well done.
I also wanted to agree with you about lost memory from childhood trauma. I have so few "childhood memories", and I know it is all due to the abuse and stress of the time. I'm grateful for the coping mechanism of this, but also sad for the childhood lost. I enjoy your writing.
