"Hello, madam/sir, and how are you this very happy day?"
A bit perplexed, you answer "Just fine, thanks."
Since you don't quite understand what it is like to be a Sailor and she doesn't quite understand what it is like to be a mere human who never gets to transform into a pretty suited sailor, this conversation is very short and pointless.
You stand around staring at eachother blankly for a while. "Sooo..." Neptune tries her best conversation starter "How are those Thundercats doing?" She can at least pretend to be interested in sports. You choose the best conversation ender in the book. "I ate them." She lifts an eyebrow at you and you see a strange twinkle in her eye. "What can I get you this mighty fine afternoon?""One ticket for the dome of happy," you say.."OH! And can I get some fries witht that?"
"Okay, that will be $2.45"
"Oh....it costs money!"
Sailor Neptune looks at you like you are a foolish nimwit. Obviously it costs money. Now what? I guess you will have to work at the arcade until your financial situation gets straightened around. THEN you can explore the park.
