I'm pretty much blind to french/english. Like, I can read a text (in one of these two) and I won't be able to tell you in which language it was written in. Once in school, in media something, we had to choose a graphics and analyze it. After writing a full page, I noticed I was writing in english, in a french school in france. (teacher was also our german teacher and is italian so I went whatever)
I started following more french people and I'm starting to randomly write in french here :x
