Rockwell captures it.  Dad and my Uncle fought in WWII and Korea.  They kibitzed each other after we played golf for hours, drinking Wild Turkey shots with beers.  Yes, I lost in golf to dad, but I always beat Uncle Bun. lol

Talk to your parents and get to know them before they are gone, but don't pry into personal details you don't want or need to know.  Be sensitive to their lives and experiences before you came along.
