In russia I was introvert but my english teacher's love of english turned to english lover and more of an extrovert. Way that insinuation works in English is brilliant and how I liked to compress what I am saying, russian is very intricate but verbose language, I found home in English though being down to the center bi-cultural, bi-lingual. Generally I feel english is so super efficient and dramatic language but russian is a feeling language kind of more precise but also heavy.
My mind being slow I prefer English and it makes me more extraverted, russian being good with close friends but clumsy with external world. 2c.
