"Hey dad, what's this trip I hear you talking about?"
"Well son, even though you're 8 years old, I've decided to spend the next 28 years walking around the world."
"Gee dad, that sure seems like a long walk. Are you sure about this?"
"Well of course I'll be taking breaks rather than doing the whole thing at once."
"Great, so you'll be able to visit me, your 8 year old son, right?"
"Nope! I've decided to add my own self-imposed rule that I can't visit the UK until I've completed my walk. Instead, whenever I don't feel like walking, I'm going to fly to Mexico and hang out there. Then when I do feel like walking again, I'll fly back to where I was and resume my walk."
"So you're leaving me, your 8 year old son, to go on a 28 year long, non-contiguous walk around the world where you'll rarely see me? And by the time I grow up we'll barely know each other? And you'll end up missing the birth of your granddaughter?"
"That's right, son! I hope you're excited for the first of 4 times we'll see each other, 6 years from now! Aren't you proud of your dad for being such a great explorer?"
