Observation
At the end of the road, we’ll look back at the path we walked and hopefully will not only see our own footsteps, but many pairs of footsteps that walked with us at many different points along the way. Some will be hard to see because they will be surrounded by many footsteps. But the important ones will be easy to spot because at the times when the crowd cleared out they were still there walking beside us making deep marks from the weight they helped carry.
