"I pick..." you start.
But then things go utterly out of your laid-out plans.
"A fairy!" you exclaim.
The minotaur jumps, startled at your choice. Obviously he was not expecting this at all. He is so surprised he feels he should reiterate his proposal and ask you if you are genuinely certain of what you will irrevocably become.
"Yes! Yes! I'm sure! I want to be a fairy!" you say gleefully. "Please make me a fairy! I don’t want to be a nymph if I can become a fairy instead. That is an opportunity I cannot pass."
"And... May I ask why?" says calmly the minotaur.
"Because fairies are prettier, younger and more powerful. They can fly! They are even more in harmony with nature!..."
"Well, not all fairies, for they are..." tries the minotaur, but you are not listening to him.
"And they wear the cutest clothes! And they can do much more magic than nymphs! They are so cute and openly magical! Please, Mr Minotaur, make me a fairy! I cannot wait a minute longer. Being a fairy is worth all the penises of all the satyrs and centaurs ion the world! I shall love being a fairy and be very grateful!"
The minotaur, understanding that your transformation into a nymph had impacted your mind very suddenly and permanently so, thus completing your transformation into a nymph, still decided to grant your wish. You were very enthusiastic for it and thought the world of it. Anything he said against it would not be heard by you. So he unleashed his magic upon you, altering your form and body e en more to allow you to become a fairy.
