In Ecuador we don't usually use the word adios to say goodbye. It is a term that comes with a sense of permanance.
Here we usually say Chau (bye) or hasta luego (until later).
Adios literally means "to God"
And yesterday Dustan's family said "Adios" to his grandfather, a man who lived 93 years and who loved God.
Adios Grandpa. And Hasta Luego.
