We walked around the neighborhood with Rosa and her family--her sons, assorted cousins, nieces, etc.--and stopped to sing a few songs at the altars to the Virgin Mary that various families had set up in front of their houses.
Whenever we'd arrive at a new house / altar, someone would call out "Quien causa tanta alegria?" and the rest of us would respond "La concepcion de Maria!". After we sang a few songs, Jorge (Rosa's 7 year old) would shout "Una iglesia sin Maria..." and we'd all shout back "No es iglesia todavia!". Basically, it means that a church without Mary still isn't a church. Take that, Jesus!!!
It was a pretty awesome night, especially because the neighborhood was small, very safe, and the kids could run around and play outside with no traffic, no random strangers on the street, etc. And I got to sit and watch the Mini-Menace wear his butt out and almost fall asleep in the car on the way home.
