General Discussion

A different language than English because it's more often used by cross-border family members around the house, especially if they're sponsoring Abuelita along with Tio Martin or Tia Guadalupe to come across in green cards and work Visas to both help care for Abuelita and help the family business.
A lot of families have lived here for 200, 250 years, before there was a border. Going to Los Angeles from Ensenada to marry a friend's cousin you met at huge family get-togethers on both sides of the border is not unheard of.
My natural born citizen neighbor married a Tijuana friend's cousin from Oaxaca and she got a green card forty years ago. And still technically doesn't speak English.
She can read it fluently, like I can read Spanish fluently.
But speaking it? Totally different skill set.
