I think you are sad for what you have lost, for what has been, for the memories, especially if they are very ill or elderly and death is a release. I am sad this week as I just heard that a local Mum died last week; she went for a run on a bitterly cold day and she didn't return home. She was found the next day having succumbed, for whatever reason, to hyperthermia. she had 4 daughters, the youngest only 8. That I find very sad.. I was and am sad that Mr.G died. He was too young to die and I was too young to be widowed but, it happens. I'm sad when I hear of tragic unnecessary deaths but I feel relieved when I hear of the death of someone who has been suffering. All a bit garbled, but I know what I mean, I think!
