When I was a child, I had the horrible, overwhelming fear of being forgotten. I could not bear the thought of my existence being erased from the world completely.
One day this brought me to tears, but my mom helped me feel better by telling me that she'll never forget me, even if she's dead; her spirit will always be with me.
This made me feel better well into adulthood. That is, until she uttered the words "Who are you?" as I stood next to her hospital bed.
