You tell the fairy that you want to go on your own even though you really want is to try out your fairy dust.
Ok, meet me over by that tree in an hour or so.
Ok.
Great this is your opertunity to see what this fairy dust does. You fly around the forest to look for things to try it on first you see a bear that is big and strong.
I will make you not that strong.
You pour some of the dust onto the bear and it shrinks down to the size of a rabbit even though it is still an adult bear.
Hehe.
Then you see a woman trying to take care of her baby. With a few sprinkles of your dust, the baby is the adult and the woman is the baby.
Man, this is great.
You see a boy and a girl fighting and then again with a use of the dust they boy is a dog and the girl is a cat and they fight even more.
Man I am having fun with this.
Than you turn a man into a woman and make a strong man is weakling and a weakling into a strong man. Then you relize that you have been doing this for a hour and it is time to go back to the fairy.
