It's a tongue in cheek what would you do one.
You know your neighbour has a reactive dog, they supervise it in the garden, it goes out about 5 times during a day for toilet trips. You also own a dog and know that if you throw the ball for your dog it will set your neighbours dog off barking. Do you a) make sure to always throw the ball for your dog every time you spot the neighbours dog in the garden or b) wait five minutes until it's been out for a wee then throw the ball as many times as your dog would desire??
