Yep.....My Grand Father told me when I was a young smart ass and came home with a bloody nose, “Son, everybody pays for an education. Some people just pay a whole lot more than others.”
Your Gramps was, as usual, smart and experienced and also most likely learned the hard way.
There is no school like the old school.
My dad, after he once kicked my ass, told me that either I listen or learn the hard way. I learned the hard way, and his way was easier in the end. That was the education I got.
