Native speaker of English & Spanish. Born in the US, technically, but we moved because of some job my dad had, I think.
He decided to stay in South America, and when I learned about certain things via friends, school, and the Internet, they happened to be in Spanish.
My parents, who I spoke English and Spanish with, didn’t really teach me certain adult stuff, so I learned through literature and school assignments (but also TV).
(So sexual topics and topics related to drugs I learned in Spanish)
I’m only native to one language so obviously that but depending on the context and whose with me sometimes another language is easier for certain phrases and feelings. Translation truly is murder because the same word in English and Chinese can have wildly different meanings and feelings.
