I see someones cane get hit by a car one time causing him to lose orientation and make an almost 90 degree turn in the middle of the road. If the cane is pointed towards or away from traffic people don't even stop anymore.

This was actually long ago but it stuck with me. Just now I realized what perfect analogy for life it is. You move towards something, something interrupts the journey and then you just continue, thinking you are moving in the same direction.
