There's something relentless
   in an old stone wall...
 But, also, cold and dead.
   One knows it will not stand forever --
       that it will go the way of
       ruins, rubble, stones, and dust --
       but, still, it can outstand any man. 
 Ivy climbs to camouflage the stone's
    cruel deathlessness,
 But then the ivy stands on the wall
    year after year after year...
