"It just isn't fair!" cried my very young grandson as he and I watched a children's video. A backyard soccer game between good guys and not-so-good guys. His righteous indignation was triggered by his understanding of what his parents had taught him of right and wrong; fair and unfair. Such was his reaction to obviously unfair play, you'd be forgiven for believing the culprits were guilty of a hanging offence.   

In my  more sane moments I know and accept [not the same thing] that I don't live in a perfect world. When I was younger I knew a lot more than I do now! Strangely though, the older I get the more unsolved mysteries there seem to be. Perhaps it's just me. Some lingering illnesses and accident injuries I understand, in that I think I know what caused them. But others I definitely do not. EG: 

• A close friend who, for decades suffered cruelly from Parkinson's Disease before dying. 

• A fellow struggles daily with multiple cancers and is now diagnosed with dementia. 

• A baby only weeks old who had a tumor on a rib. 

• A close friend whose arthritic pain is just debilitating as are the affects from some of her medications. 

There are more.
It seems to me there are a number of options to consider about such situations. Two immediately come to mind -

First is that I can't transfer a person's  suffering from them to me. Regardless of what it does to me to watch things take their course.

Second is I can be timely company when that is so important. "You're always there for me" is the highest compliment one can receive, because this life is unfair and too hard to deal with on my own all the time. I can recall many times when rising to the heights of my own understanding didn't lift me very high. Professional support is a wise move when life just isn't fair.
