As we go along life's way, various things can happen. We can get lost. We can get lost and found. We can rest and start again, stop and remain, "wander aimless as a cloud" or navigate with GPS precision and purpose from waypoint to way point.
We can confront strangers, meet old friends, sin k into valleys and climb the highest peaks. Things can go as planned, but also surprises can leap out and change, not only direction but even a destination...
