Para que Julieta llegue a la fiesta, solamente pasara unas casas y albores.
Translation:
For Guillermo to get to the party, he will pass by the fountain, church, road to bridge and Juliet's house.
For Marcos to get to the party, he will pass by some houses and buildings, the church, the road to the bridge and Juliet's house.
For Juliet to reach the party, she will just pass by some houses and trees.
Explanation: Neither of the people will pass the bridge because then you would reach the city and if you try to go up, the river will still be there connected to the water under the bridge therefore they all have to pass Juliet's house
