Yogi Yogi:
What you are all failing to realize is that there was no fire! The women 'smelled something' that indicated there may be a fire somewhere, and they erred on the side of caution!
I don't know about you, but I have been in similar situations before inasmuchas I have 'smelled something burning' and 'go investigate the source' before I decide what I should do. These women immediately started evacuating the children!
That is not the point Yogi.
THIS time there was no fire, lucky them. If there was, that same day, they would still have been understaffed and not been able to take all of them out at once.
