No one wants to sleep in or near a pile of dung, after all.
amn guys, you have to remember one thing. The cities of those time period, were encumbered, dirty, horses were common in the street, where the nobles would not care of steping on the child of a paysant. Horse bulls dung, were common in the streets, to a point if you look at the history of loius 14, it's not only the rotten food that were thrown at his personal guards and the mousquetere, but also the horse and bulsl dungs. The game is a bit to asepticized (probably not the right spelling there) where everything seems clean, but you can be sure that if you were in a city of that era, the streets would be dirty as hell. An example of what it would be like is actually Vehl, London and Paris at the same time period as the architecture of the game, didn't have the entirety of the city streets covered with stone. Most of the city streets were dirt streets, where it was uncomon -not- to step in a mudd puddle or dung. Now I know this is RL vs Game, but if you think about it, in any countries that had the same time period, and even todays that are still not at the same status of civilization, the streets are dirty, filled with animals and what comes with them.
