Your grandfather sounds like fun. I think it's something they are born with. My oldest grandson told me when he was four, that he liked to see his momma in the kitchen, cooking for them. You can get away with that when you are 4 or 94.:')
He's a hoot. He's first generation off the boat from Italy. When they came to the country, his mom didn't speak a word of English. He has amazing stories about the Depression and just amazing life stories in general. I want to start getting them down on paper, and that won't be hard because he sure loves to tell them.
