Together for life, we live or die it makes no difference, togetherness we can achieve what ever we set our minds to. I really liked the story, was hoping they did survived but life is what it is, you win some and you fail some that's part of life.
Hivers we are together no matter what.
The difference between us, mark and jon is, we set a goal and try all against all odds to achieve it. Mark could have bring his friend to come work as a driver in his company that way they did be together but quitting his? Hmmmmm. Wisdom is needed in every aspect of life.

Good morning from this end.
