These rocks-- round, not suitable for skipping centuries of rolling along the stream's flow-- all the edges ground smooth in the most ancient of ways.
These ones making walking difficult-- when one rock doesn't fit well with others it rolls and shifts; not wanting to find its place with the other rocks, making footing unsure-- unstable.
I see this one; there-- unconcerned with the fit. It has an edge or two-- still.. as of yet not ground smooth. It stands out-- not for the safety of step it can provide, but for it's utter uniqueness--
a stone like no other; with it's almost chosen-rough edges.
