You decide to make a gender bender potion. to do this, you need hair frome a male and a female. The male part is easy, but the female part is a bit trickier. However, you remember that you have your girlfriend May's headband in your bag. You collect enough hair from that to be able to make 4 vials of the stuff, each one needing a full dosse to swap genders, but before you can test it out, you have to go to your second class, English. You feel like this is a good class to try to use the potion, as you have a substitute teacher who really doesn't care what you do.
