My native language (born and raised) is French, I was born and live in Quebec, a (mostly) french speaking province (altough living in Montreal pretty much requires speaking english and soon arabic). My mom plugged me in front of Sesame Street as soon as I could speak, I was involved in a language exchange with an english-only speaking family at 15 in Woodstock, Ontario, Learned english at high school and went to work for an ISP in 1994 (mostly english speaking customers). Dated an english-only supervisor when Videotron went into a lockout, some of my girl friends only spoke english, Tried to learn Spanish while in CEGEP.
My younger sister was a little more fortunate as she went to an english-only immersion school where everything including geography, history and mathematics were done only in english. (and she speaks it way better than I do, she has *no accent whatsoever* )
One of my "she's a girl and my friend but not my girlfriend" is teaching me Ukrainian and Russian, but I'm pretty sure it's gonna get me nowhere unless I move to Russia or Ukraine or want to visit Tchernobyl as she's currently doing...
Even If I'm french speaking, all my OS's and devices are configured for English just because they're aren't any translation mistakes.
(If I made any syntax or any other errors, keep in mind my primary language is french)
