Trying to help
I feel certain that the dog would not have bitten the senior recipe tester. That is, if the dog had not thought the senior had pushed it down the stairs.
The senior, it should be said, is not prone to violent acts, towards cute furry animals nor anyone else for that matter. Yet this poor creature saw need to attack the senior's ankle in rather a vicious, blood-drawing fashion.
Shortly after it fell down its own front stairs.
Surely, if it had not fallen down the stairs it wouldn't have even considered that the senior recipe tester had pushed it.
If the dog had not gone out of his front door it would not have fallen down the stairs.
If the senior had not summoned the dog's owner to his front door, the dog would not have escaped out of said door that morning.
If the senior had not needed to turn off the water to the house of the dog owner, he would have had no need to summon the owner to his front door.
If the dog owner's dripping tap had not gone from dripping to steadily running, the senior would not have had need to turn off the water to someone else's house.
If the tap's washer had been changed sooner, the tap would not have gone from dripping to steadily running.
If a large volume of water had not have been running through the retaining wall between our house and their house, the senior might never have considered that the tap's washer should have been changed sooner.
If a large puddle had not developed on our driveway, the senior might never have realised that there was a steady stream of water continuously running through the retaining wall.
If the senior had not driven the car through a hitherto unnoticed large puddle of water on our driveway...
well then, the senior recipe tester would not have been bitten by a dog.
