...was the last of the old 'normal'...
My sister died suddenly. She was 30.
I still miss her and think about her often. The strangest thing is that there are no terms for the status of having lost a sibling... like there are widows and widowers, orphans etc. Perhaps it is too hard to name it?
I sometimes wonder if she's come to live with me in New Kitty's head -- New Kitty is pretty bright for a cat, and if reincarnation is true, there is nobody more likely to come back as a cat.
