Two cars with one dog in each. They both have their heads out the windows, having a conversation with each other. Sandy and Who just met when their owners stopped at a stop light. The air was soft and warm that day. You could hear Birds chirping nearby, and the sound of cars. The dogs conversation sounded like mini barks to humans, but to the dogs it was pure conversation.
The owners happened to be going to the same shopping center. When they arrive they park next to each other so the conversation could keep going.
Their owners are a man and a woman. They are not married. As they get out of their cars, they smile at each other and talk about their dogs. They arrange to meet again to take their dogs for a walk together. Sandy and Who are both pleased about this development. During the walk the dogs develop a romance similar to their two owners. Eventually the owners get married and Sandy and Who get married as well. They all four live together happily ever after.
