I used duo lingo before my 2 recent trips to the Dominican republic. I impressed everyone that I came in contact with! Everyone was amazed when I was able to to pick up on what everyone was talking about. It’s like I was the unofficial translator.
Not only that, but I knew when my people where being talked about or schemed on. Everything was on the up and up when i was around. It was Amazing. And I learned it all within a few weeks before the trips. And most impressively, it was free! If you click my link, I will get some credit for introducing you to it. https://go.magik.ly/ml/h0uk/
Reading your article helped me a lot and I agree with you. But I still have some doubts, can you clarify for me? I’ll keep an eye out for your answers.
