Imagine being so drunk that you end up in the wrong house. A lady was sleeping in her own house when she heard the sound of running water (not something that would inspire any sort of security or trust), and called the police. It turned out there was indeed an intruder in her own house, somebody who had taken a shower in the house. When the police turned up, they found the man, now dressed, sitting in the verandah. It was then that the man realized that he was in the wrong house - after being totally drunk, he entered the house thinking it was his own house, and then took a bath to sober up.
It was after being confronted by the police that the man realized that he had entered the wrong house, and was then very heavily embarrassed about what he had done (link to article):
The man got lost on the way to his house in Katherine on Wednesday night. He walked into the home and took a shower in an attempt to sober up. The 34-year-old householder was asleep upstairs. She woke up, heard the water running and frantically rang the police. When officers arrived, they found the 42-year-old sitting on the woman's verandah - dressed again.
The man was taken into protective custody to sleep off his big night. "The woman was just happy for us to take him away," Supt Shean said. "She thought he was a burglar."
