Permanent transformation, and you can't hide it forever. Your voice remember?
Um, what? The length of your vocal cords are largely determined by your gender. The properties of your voice aren't bound to your body the same way your conscience is. Unless you're getting some halfway surgical gender swap, your voice will change.
Also you said "for a week". You're not Darth Vader. You're not allowed to alter the deal.
Perhaps you think you are being treated unfairly? --- http://i.imgur.com/K29ku1D.png
Guys it isn't possible. You have responsibilities, what are you going to do, show up at college and say your name is ( ).
Good luck with that and have fun getting fired if you workXD
We do what all gender bending series do. "Hello students, this is *insert masculine/feminine version of original name* and they will be staying here for week." --- <('__'< ) <( '__' )> ( >'__')> ^( '__' ^) (^ '__')^ ^( ' o ' )^ Official Ferrothorn(Spahgetti) of Pokemon X/Y boards.
