Visibly stunned

I started using your podcast when I was 22 and I’m 27 now, so it’s been a massive part of my learning process. I actually got a chance to go to Portugal and was pleasantly surprised by how well I could communicate with the people there. I had to use it much more than I had anticipated, and in some of the towns we went to it was an absolute necessity. People were visibly stunned when I told them I was American and asked me how on earth I had gone about learning Portuguese.
