It had been rumored that Ms. Johnson was a lesbian, acting brutishly and looking more mannish than feminine with a buzzcut hairdo and all ... and the rumors were correct, even though she never told anyone. But that didn't stop her from checking out the other female teachers and she had always had her eye on one in particular. Her name was Kelly Robertson. She was only in her mid-20's, having just finished college over a year ago, and always looked trim and fit. But she was the straightest person Ms. Johnson knew. It was common knowledge that the woman was against gay rights and was one of the few teachers in the school that openly discussed her political views on almost everything, and those views were entirely conservative. But despite all that, she was just so damn hot. And now with what could actually be a real wishing stone, Ms. Johnson could make Kelly hers.
So after Ethel tried to stop her and failed, Ms. Johnson said "I wish Kelly Robertson was my lesbian lover." The stone glowed, granting her wish.
