American Accent: The Unvoiced TH

Where did you get your first English lesson from? Do you remember how intense it was? For a good number of us,  we started learning as early as our Nursery years up until we finish College. I, on the other hand, experienced my first serious, strict, and no holds barred English lesson under the tutelage of my mother, Delia. My mom would always say to us when we were younger that "I have only the best intentions for you."
