> In my case, I speak two languages every day, and have done so for decades. I often say or write things that are syntactically incorrect in both languages. I also have spoken two languages (EN/PT) almost every day for 15 years, but it's my spoken English that, at times, adopts the syntax of my Portuguese. I'm very careful to not let English "corrupt" my PT for fear of sounding off, but I'm wondering if I'll end up following your lead in about 10 years (mixing up both).
