Intro
Meeting at the utility pole in the morning
Example 1
Meeting at the utility pole Oh, finally made it? Mornin'.
During a stone-kicking match on the rice paddy path He-yup, my win. I guess being born two hours earlier really counts for something. So, you're buying the Ramune.
Whoa, Guest, you're wrong. There's no "only" about it. Those two hours are huge. You just don't get it~
Arriving at the bus stop and sitting on the bench. Both pop the glass marbles to open their Ramune bottles with a 'pshh' ...Here, cheers. Clink. The two start drinking as the bottles make a light clinking sound Man, that's good! Ramune bought with Guest's money tastes the best.
