I understand what you're saying, Vivi. Its just hard to not think about those things given the gravity of the situation. Considering the type of person I am, I act very quickly and calmly under pressure, which I guess is good for being a mother, but it surprises me because I'm not that type of person at all. So I'm pretty sure in the situation I would make the switch without sitting there pondering it before its too late. But I do know myself well enough to know that afterwards I would constantly be thinking about that stuff. I'm not as stable of a person to just say "I saved four, its what I had to do" my brain would always be wondering what I could have done differently, was there any way to save them all, did I do the right thing. That's why I said I would be miserable for ever afterwards. Its an awful thing to live with either way, because my brain wouldn't be saying "you svaed four people" it would be saying "you killed someone".
