My grandfather was a salty old cowboy born in 1906, and he was further seasoned by losing siblings young, the Great Flood of 1927, the Great Depression, having a brother fight in WWII, etc. His wisdom could therefore be rather, um...Coarsely homespun.
For instance, one of his favorite sayings has stood the test of time when applied to farm animals, pets, and kids that were all 'finicky' about what was served to them: "Leave it right there. They get hungry enough, they'll eat it." They always would. And I learned to never, ever complain about what was served at a dinner table, lest I 'sit right there till I eat it'.
My grandfather was also integral, so much so that his epitaph was, "Lived by His Word". If he said something was so, you did not have to doubt it. He was so adamant in this respect that the 4th generation from him still values integrity.
He passed away in 1999, and my heart still cries for him.
