Emma asked a hearing person the following questions:
Emma: “Why do you want to learn sign language? “
Alex: “To widen my horizon. I am interested in all languages, but sign language is very different from spoken languages, because it seems so natural and logical.”

Emma: “Did you think, that there is only one international sign language or did you already know that each country/region has its own sign language?”
Alex: “No, I knew that there are different varieties of sign language.”

Emma: “What has changed since then?”
Alex: “I noticed that the several sign languages are less different than I supposed them to be, because deaf people from different countries can surprisingly well communicate.”
