It’s like I brought her along as a model.
She was with a three-car party of Spanish speakers from Great-Grandma to babes in arms. As we huffed our way up the stairs (notice I arrived second…) I got to listen to many conversations between them all.
You could guess how it worked – the older ones spoke only in Spanish and were answered in Spanish, the middle aged parents sprinkled some English words in when speaking to the younger ones (like they couldn’t remember a Spanish equivalent), the teens sprinkled some Spanish words in when they were talking to each other and the ones under teenage basically spoke English except to the very oldest.
It was a perfect small novella in cultural acquisition.
