I have heard it said that if you are able to argue, dream, or meditate in another language, this is a sign you have become fluent in that language. This seems like a reasonable way to gauge progress. What is your opinion on this?

I am an English teacher and ASL tutor and I can confidently say I can effectively argue in both languages. :)  I currently have room in my schedule for new students. I don't plan on arguing with my students (unless you want to test your level of fluency!), but I am ready to meet you and help you along your road in learning English or American Sign Language. Feel free to request a 30 minute trial lesson on my profile page:  https://www.italki.com/teacher/3239587. I look forward to meeting you!
