A puppy provides an answer.

As Frank mused, a young woman came out of the house next door, holding a puppy in one arm and her phone in the other. She put the dog down and continued to chat, obviously much more interested in her conversation than her pet. Frank watched, taking in the slender girl's pretty petite body, nicely displayed in a clingy sundress.

The puppy waddled happily about, snuffling and exploring, and made it's way into Frank's yard, the girl oblivious to it's movement's as she continued her phone call. Frank looked at the puppy, and back at the girl, and grinned as an idea occurred to him.

It was the work of a moment to quietly lure the puppy onto his patio, then pick it up and carry it inside. He scratched it's ears as he poured a glass half full of water, then sat the puppy down and poured the water on the bottom of some floor length curtains and on the carpet, leaving a dark wet spot. He grinned and scratched the dog's ears again, then raised his voice in an angry yell.

"What the Hell! You mangy mutt! Pissing on my carpet! I'll skin you!" He grinned, scratching the dog as he heard a squeak of alarm from next door.

"Baxter! Where are you Baxter! Come here boy! Baxter!"
