One Monday morning, after Grandfather had spent the weekend with us, I complained that I didn't want to go to school but instead to be with him for another day.
Being the wise and loving man he was, he put on a screwed up grin and whispered: "Son, you take a bite off my twist and chew it. That will make your face turn green and your Mom will believe you when you say you're sick and you won't have to go to school."
I never used tobacco again!
