Time to go?

A's Auntie "K" passed away yesterday. It was very unexpected, and very sudden. And, as we deal with the loss, I have to wonder...

What is easier to deal with? A sudden death, or knowing that you are going to die?
Take in point, my Grandma. She was diagnosed in March with terminal lung cancer. We know her end is coming, we just don't know when. But, it is easier for us relatives to 'deal' with it. I know she's leaving soon, so I've made an effort to spend time with her, ask her the questions I need to ask, and tell her I love her. I will be sad when she goes, but I'm sure I will be at peace with it. She, however, is having a hard time facing her own mortality. I saw the same apprehension and fear in my girlfriend, when she passed away from cancer about 9 years ago.

On the other hand, Auntie's death yesterday was quick and sudden. There was no time to say things, or spend time with her. You had to take what you had given. And while it is difficult for us relatives to deal with (shock, possible regrets), I have to think that she didn't go through what my Grandma is going through.

This has me thinking that it's probably better to go quickly.
It also has me thinking that life is too short, and that I had better get to my bucket list while I still can!
