When interacting with individuals form different cultures than yours, people tend to highly underestimate how much differently these individuals from a different culture “see things” differently.
This is a big mistake. It is often the main reason you experience cross-cultural relationship breakdowns.
To be successful with individuals from different cultures, you very much need to understand what their values, beliefs and attitudes. That is the first step to earning their trust.
Showing respect for their culture is critical to gaining their trust.
If you do, they will tend to appreciate and respect you for taking the time to understand them and respect their culture.
Without that trust, they will likely not be interested in building a relationship with you.
