Ami,
When my father was in the hospital and died, I remember my aunt (his older sister) just breaking down and crying. More so for the fact she was the only one left of her siblings (6), than my father's passing. At the time it slightly offended me, but as I get older I understand it more. With each year, century, etc, the passing of time changes who and what we are. I use to be a daughter, then a sister, now I am a mother and grandmother. NOne of the people that took care of me are left, I am the caregiver and matriarch of the family and I DON"T LIKE IT!!!
I then go through and think of all the friends I have known over the years, some still here others I have no idea where they are. They all seemed so important at one time. I worked with elderly and could certainly empathize with their losses. The hardest thing was when they were ill and I would say "you need to take care of yourself so you can get bettter" and the reply would be "Why". I never had a good answer for that.
I know I have strayed far from where you were going on your subject, but it just brought this to the surface for me. Love who you have in your life now, let go of those who hurt you.........my whole point was, life is too short. Take care of you Ami, you deserve it.
