While not as multilingual as I'd like to be, I have been trying to at least get aquainted to different languages, and discover tools such as Duoling that can take me farther.
French
In middle school, because my small choice school didn't offer languages, I self-studied French I. I continued in high school and I am now on French III, doing great and enjoying it
Romanian
I am passively bilingual in Romanian, meaning I understand the language but have limited ability to speak or write it. I have learned the special Romanian diacritics and spelling rules, which enable me to write on dictation, and I hope to further improve. I am now reading some short stories that are unavailable in English and have an intriguing topic (growing up in Communist Romania before the 1989 Revolution)
