What if the train is just YOUR perception? What if in reality, the train (a metaphor for a big moving object that can kill people) is really a mosquito biting them and it's just not really serious (does not have the impact you think it is going to have)? What if your perception is skewed?! How do you know that you know the "truth" about the relative seriousness of various issues impacting people (what you see as a threat might be the 10th item in terms of magnitude)?! What if the people just don't care about mosquitos?!!
P.S. I'm talking in the most abstract terms and not saying anything specific. Just a food for thought.
