A simple answer could be because I didn't want, but that is not necessarily the case. In this story, Haz was looking for the exact reason why Mao didn't complete the ritual. The same thing happened a night they came back from the beach and Mao invited her a bottle of wine, but he decided not to close the act either. Nevertheless, the reasons for those two outcomes were different. The first one was because there were other people around, and respect is before satisfying any passions. The second one was because of a principle Mao promised to stick to: No matter what, never sleep with someone who is sleeping with other(s). Haz was a mix of Japanese and Cuban, interesting mix to consider, but as tempting as it sounded, it shouldn't happen at the time.
It is hard to explain that to the other side, so sometimes it is better just to stay quiet although that bounces her back to you and you have to pay for the differential karma produced by the silence, by dealing with a weakened siren.
It is interesting that in the first event in the Saga with Haz, there seemed to be a green light but external circumstances prevented the final from happening, and in the second it was a misalignment of principles the reason. Generally speaking, when those two things converge positively, I call it The Moment, and I like to be in The Moment, I want to be in The Moment.
