We've enshrined the purity, sanctity, value, and importance of bringing children into the world, yet we don't discuss death. There used to be an enshrined period where mourning was a necessary part of going through the process of grieving; death wasn't considered morbid or antisocial. But that's totally gone.
Getting over someone is a grieving process. You mourn the loss of the relationship, and that's only expedited by 'Out of sight, out of mind.' But when you walk outside and see them on a billboard or on TV or on the cover of a magazine, it reopens the wound. It's a high-class problem, but it's real.
The fire was followed by a period of grieving and then by an incredible lightness, freedom, and mobility.
Certainly, we all wonder what is beyond, and when you lose a loved one, I think part of the grieving process includes where that person might have gone or if you'll ever see them again. I think it forces you to look up to the sky, to the cosmos.
I don't believe in regretting - one should try to move on. My mum was good at that. She was deeply in love with my father, and he died when I was nine. She remarried, and her second husband died, too. I saw the grieving process she went through. My mother had this way of moving on. It was a fine trait.
