@BillRM,
Now that u bring it up,
I remember seeing the true story of some South Pole explorers,
in the early 2Oth Century. Thay were said to have hated one another.
1ce one of them got lost on his South Polar exploration
under hazzardous circumstances; he was missing for a while.
The other explorer went to rescue the fellow whom he hated.
Eventually, the missing explorer turned up safely.
The rescuer was forever lost; s
imultaneously, he was never found. He did not hate him
enuf.
My memory is a little vague on the names & details.
