As we strolled around the city we came across a square that had the canal on one side and the church on the other.  And in between these two things were children playing soccer.  They would use parts of the church structure as the goals.  I really wanted to jump in and play but I thought I better just watch.  Occasionally one kid would kick the ball too hard and it would roll towards the canal.  Lucky for them, all the people walking by would stop the ball each time.  Not sure how many balls they have lost in their lifetime.
