Life is a biochemical accident and so is death. Those who have gone before – my parents, my aunts and uncles, some cousins, some friends – all had an impact on my life that continues long after their deaths, not just an impact on me, but on my daughter and, through my daughter and me, on my grandchildren.
My idea of "heaven" is that, when I am long gone and they are parents and grandparents themselves saying, "Oh, but my Granna could…", "My Granna taught me…", "I couldn't do that because my Granna would be so ashamed of me…", "You should have seen my Granna…" I loved my Granna so much", "My Granna loved me and was so kind…" and so on.
I am probably fooling myself. In any case, I shall never know.
