No, I lost a lot of Spanish when I was younger. You see, I initially spoke Spanish, Filipino and English. BUT because I was taking longer to develop a (noticeably) working phoneme and grammar bank in any of these languages, an idiotic 80s speech therapist told my parents to only let me speak English. Thus my trilinguality was lost. DAMN YOU 80s SPEECH THERAPIST!
Since then new research has found that what was happening to me was a NORMAL indicator of developing fluency in more than one language. Anyway, I'm regaining my Spanish, it's just a pain to have to learn again what I once knew naturally. I don't use it much to people I don't know though because I am easily embarassed.
