What they don’t tell you about speaking multiple languages is that your brain does not in fact have a box labeled Spanish and another one labeled German. Instead it has a box labeled “Not English” and sometimes when you’re talking or writing in one of the languages you speak it will just start pulling random words from that box.
For some reason, my brain loves mixing up exactly the languages I'm still learning. German and English mix occasionally, too, but I blame that on the increasing amount of anglicisms in German. But five sentences into speaking Spanish I will literally just start talking in Korean for some reason like???
