Mark and Sara are in China. Sara asks Mark if he wants to visit the Great Wall with her. Mark is tired and doesn't really want to go, but Sara convinces him.
Sara: I'm off to the Great Wall. Do you wan to come?
Mark: We're here on business!
Sara: We've got a whole week here. Let's get to know the country better.
Mark: By going to a tourist trap?
Sara: You'll change your tune when you see it. I hear it's amazing.
Mark: I'm ready to drop. I've got jet lag. I think I'll stick around the hotel.
Sara: Exercise and fresh air will work wonders for your jet lag! You'll definitely get a second wind.
Mark: I don't feel like sightseeing.*
Sara: Don't be a couch potato! This is a once-in-a-lifetime opportunity.
Mark: Okay, let's go see the Great Wall.
(at the Great Wall)
Mark: Wow, this wall is long!
Sara: It's over 4,000 miles long.
Mark: I feel like we've walked about 2,000 miles already. I'm hungry.
Sara: Let's grab a bite!
Mark: We passed a woman selling dumplings about a mile back.
Sara: Okay, let's go find her.
