"It's very useful," Romilda said with a grin. "I told my cousin that he liked boys before he even figured it out himself. Doesn't work so well on girls, but maybe that's because I'm not into them? Anyway," she said, stepping back a bit and grinning at him, "If you wanted to know if anyone was into boys, I'd be able to tell you. Not that I approve of you cheating on Tracey."
She got a bit more stern at that last bit. Romilda tried very hard not to interfere with other people's relationships, enjoying seeing others' love stories play out as they should. She would only interfere on her own behalf if she was madly in love and the other person loved her in return, because love stories only worked if they were real and true.
But who knew, with Tracey. Romilda knew she was openminded, rather like Romilda herself. Maybe Tracey was dating a boy who liked boys specifically because she could have a threesome with another boy. Well, not because of that, but Romilda could see how that was part of the appeal.
