I am in fact aware of a young woman who dressed up as a fairy for homecoming week and has been seen multiple times wearing a T-shirt stating that "All the cool girls are lesbians", but was evasive when I questioned her sexuality, claiming that she merely bought the shirt because it was on sale at a store.

She was evasive when you question her sexuality? I suggest questioning her on her weight and age too, by way of a control. :)
