Can you send me a picture of the page in the story that has that sentence in it and then maybe I will be able to answer you
I would say that learning another language is the most important for communication especially if one is in the country where the other language is spoken and is immersed in it then to be able to survive then one must learn the language and also the process of learning it requires reaching out to the local people and relying on their assistance which bonds one with the people of that country.
The quotation that best distinguishes alex from other characters is that "he was seen wondering aimlessley around in the neighborhood" I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.
