The case was in France. One young man lived on the first floor in a bustling neighborhood and in the toilet he had a glass in full height, coming straight out to the street, the glass on the side of the street looked, naturally, like a mirror... Well, he loved to fuck looking at the passers and all this city turmoil. One day, he left for a business trip and left the keys to his friend to look after the house. A friend had a sense of humor and changed the glass in the toilet for the usual one. The owner was in the wharf when passing by passers started pointing to him with a finger =)
