My 81-year-old grandfather always says that he's still not sure what he wants to be when he grows up. He's the kind of guy who drove school buses full of screaming children when my grandparents first moved to Florida, just because he wanted to, later driving buses for Downtown Disney patrons.
I'm only in my late 20s, but I feel that too — who really knows what they want to be or do when they "grow up"? This next retired fellow seems to share the same sentiment.
