Stubborn by Nature

Vines all tangled up in each other, They slouch lazily into the others's arms. With renewed passion they climb HIGHER HIGHER HIGHER. UP stony walls, masoned by the strict laws of engineering, Base equals width times height and all that. But these vines like to break down the careful structure, Because while the stones are old and strong, Vines can hang with thousands more years of strength. A winter wind sweeps silently through, stopped In its tracks by a vine-covered wall, Where these finicky vines, mercurial vines, Shun one another, cling tighter to the masonry as they shiver. They'll whither soon enough, their dried remains Turn to mulch under a careless pair of boots. If they had clung together, could they hold still, And break the damned wall DOWN?
