Wolfy

"Zdravko is a retired widower. His daughter never visits him and he lives a solitary existence. One day, he notices that people who walk their dogs in the park stop and chat. So he borrows his neighbor's dog, Wolfy, takes him to the park, and his plan works. He finds people to talk to - but he forgets about Wolfy and the dog is gone. What is he going to tell his neighbor?"
