Life is full of choices and lines to either cross or draw in the sand or to acknowledge. It is up to each of us to discern when one becomes another.
There is also apathy and keeping your head in the sand (which can lead to the circumstancesof the poem above) and that's counter balanced with being stressed, over extended, and not enjoying our time on this planet. I feel too many Americans are disconnected from life and as long as the tv has entertainment, they have their beverage of choice to drink and processed food to eat they are happy to be oblivious and wild walk down the gangplank or onto the bus without complaint. The rest of us are left to scratch our heads and wonder and stress over things we may not be able to control.
It's to each of us to determine where we each sit on it.
