The biggest feeling is that an introverted person becomes sociable, and an inferior person becomes confident because of language. This may be a bit exaggerated, but the fact is that the fastest way to improve your language level is to communicate with local people, so in the process of speaking and speaking, your knowledge will become rich. Secondly, because of contact with different races and nationalities, some are radical and efficient, and some are naturally cheerful. Drunk people will become more tolerant today. Finally, when you meet someone who doesn't know a foreign language, you can help him with the language, perhaps by ordering a meal at the airport and explaining why this thing can't be taken on the plane, but because of good intentions, your heart will become softer and more confident.
