How much is enough?

Dad died at the age of 65. I am now 66. Mum was 95 when she died. It is now 6 years since dear friend Pam died at the age of 60. It was way too soon.

The other day a friend brought us some mushrooms he'd picked. They looked a bit dodgy but I cooked them up and ate them saying to the family, "It's been nice knowing you." They look at me wryly when I say things like that...
So how much is enough? I have grieved over the early death of family and friends, wishing they had had more time with us. On the other hand Mum was more than ready at 95. She was weary and would say, " I ask the Lord every night to take me home," to which I would reply, "But I like having you around." I knew I would never be ready for life without her.
My father- in-law was profoundly deaf and quite frail before his death and sorely missed his partner of nearly 70 years. He expressed disappointment on a number of occasions when in the night he thought he was going to die but then woke up the next morning, instead of 'waking up dead.'
So when is it time and how much is enough? "She's had a good innings," people will say or, "At least he didn't suffer." Who decides these things? Is every day a bonus?
There are dark days when I think I've had enough and would gladly be done with life, and other days when life is glorious, full of rich and wonderful things.
Other times - like the mushroom eating day - I am grateful for all I've had and give thanks for life in its fullness, and, thinking of Pam whose life ended too soon, see each new day as a gift. May it be so for you, dear reader.
