Foreign. While foreign (rightly so) often brings up images of things outside of your own nation, it can also apply to things outside of or different from your normal environment, or even something which is out of place in general.

This picture was taken in Costa Rica this past January.  This is inside the Basilica de los Angeles in Cartago.  The Basilica is the largest Roman Catholic Church in Costa Rica, and people come from all over the country and other parts of Central America to this church.  They fall to their needs at the back of the church and shuffle down the aisle, praying.  Some use their rosaries, others just pray. This kind of devotion and expression of faith and spirituality has become foreign.
