Oh, I. Have never shared before. Russian is my first language but I have lived in Germany and at the point of my first coming to the States my English, though good and I used to teach ESL to teens, was poorer than my German. But now I do not use German and it is allgone as is French which I also used to know well and spoke when living in Montreal.

Ex was born in Germany but is ethnically and linguistically Russian.

My son is perfectly bilingual French slash English with some knowledge of spoken Russian but he is not literate. Maria and Julia are also not literate in Russian especially after they stopped living with me because ex speaks English to them. Maria takes French in HS and Julia... Julia takes MANDARIN in MS. I have never even attempted to learn an Asian language but back when I saw the girls still, Julia used to say that Mandarin was easy especially the grammar. I was amazed. Also back when I saw the girls I used to help Maria with her French and everything came back to me easily without effort so I came to believe than unused languages just go into a dormant state, ready to be retrieved when needed.
