The mark

Scratched the spot paint fell, nail head rusted

Pulled the the spike the nail busted

Drove another, wood gave way

Hole grew bigger, now a surgical display

Beam rotted, chewed by time's teeth

Leaving beneath an empty pulpy sheath

A wall disrobed, naked and bare

Skeleton decayed, bones to tear

Corrupted column revealed a bad tooth

When pulled, down came the roof
