"It's been years since a human has visited me," the ogre said.
A pause, and then, "Yes. At least three decades."

The human said nothing, but continued to walk into the the ogre's dwelling.

Sniffing the air, the ogre recognized the scent.
"Well!! It seems the last human ..."

The human stopped walking, raised the shotgun and fired, thus removing the ogre's head.

"...was my father." the human said.
