"Alright, Genie... I have a strange wish... will you grant it anyway?" you ask, a bit shy.
"Of course, Master. I can grant you anything." she answers.
"Well... ugh, this is sort of embarassing, but... I want to become an astronomical body, like a planet... or a moon... or something like that..." you tell her, expecting a laugh. But instead, you receive a confused answer.
"A celestial body?..." she says. "That's a very odd request... I can grant it, of course, but why would you want that?" she asks.
"I'm not really sure... I just want to be big, bigger than a city, a country, a continent, hell, even this very planet! And there's nothing bigger than that, except for a planet... or a star... being a giant sphere of thousands of kilometers of diameter... I know it's strange... but I want it."
"Well, Master, I can grant you your wish of becoming a celestial object, but as I told you before, you need to be more specific. There are many kinds of them, so please tell me what you'd like to become."
Again, she puts you in a situation which leaves you thinking for a while, but you eventually come up with an answer to reduce your options.
