They say that the shortest path between two points is a straight line. But what happens if that path gets blocked?

When sediment impedes the flow of a river, it redirects, zigging and zagging instead of following a straight course. What looks to the crow like meandering, is to the water the most efficient route from source to outlet. Nature finds a detour.

When two points are destined to touch, but a direct connection is impossible, the universe will always find another way.
