It wasn't a flood, just some irrigation water. It made Rory a lovely lake, and he didn't have to put a missage in a bottle hoping we'd come rescue him. Rory lives by himself in a pen with a hill and two sheds. His hill commands a sweeping view of the whole place, and Rory imagines himself ruler of all he surveys. Which is why he lives by himself; otherwise he fights and fusses and paces the fence and busys himself keeping the other boys away from his corner, and he neglects certain neccessary tasks such as eating.
