The Saturday that our health project team left La Paz the priest from the cathedral blessed the building where the orphanage is moving into and we were invited, the nun knowing that we were leaving, as guests.  Our team of aspirantes has been working every Saturday cleaning the garbage and piles of refuse and moving huge piles of dirt.  Saturday a group of students from one of the local colegios arrived in conjunction with the benediction.  The nun did not know they were showing up but happily put them to work.  I spoke with their professor who said they didn´t know about the clean-up of the orphanage and would henceforth show up every weekend until the building was all cleaned up.  This is what sustainable development is all about.  We started the ball rolling and the locals then took over to finish the project.
