The snail


I just stepped on a snail, poor thing, I felt bad in fact

It must have felt like a turtle trampled by an elephant

Yet evolution is at work, by taking this slow snail out

The future belongs to faster snails with harder shells 

or snails who hide under a rock and don't crawl into my path.
