Harmony in emigration does not only start with documents and language - it lives in relationships with people. Habits on an interpersonal level build social inclusion, confidence, a sense of "I am not alone" and, most importantly, a new quality of life in a new place.
When you are in a new country, it is especially important to be able to communicate your wants and needs clearly. Not to please. Do not conflict. It is important to be assertive but respectful.
