I can be very polite and friendly to people in everyday life, but that doesn't mean I would trust them. For me, it's just easier in life to rely on myself than others. Way too much can and has happened. In survival situation, yes people will band together for the good of the cause, but ultimately, it will come down to survival of the fittest if drawn out. Starvation along with other things, especially if it happens to ones kids will make a person desperate. You just never know what a person's trigger may be.
