I never get the impression that Shep is going without food or water, but he sure is watching the people on the bridge go without.
I guess it just seems that if it were me, I would have left that bridge immediately when I saw there was no help. Walking down the road would have been much better than just sitting there. According to Shep that is no longer possible for these people, because authorities are preventing them from going to the next town. But Shep must be able to get out of there. He also screams that he doesn't know where the authorities are right after telling us that they are preventing people from going to the town. Something just isn't making sense to me about the whole scene.
Well .. you and I would have left - but these people have lived on the public dole for so long - they don't have any incentive to help themselves.
This is the legacy of the democrat-run NO - people expecting the govt to pick up the tab for everything and doing nothing for themselves.
There truly are people who need help - but more people need to be TAUGHT to care for themselves.
