It is always a good idea to increase cultural understanding and interpersonal communication skills. Developing these skills starts with learning more about your own perceptions, cultural background, and communication style.
The way we behave and interact with others is influenced by our experience, the communities we grew up in and interact with, our understanding of our own communication styles and ways and those of others, cultural factors, and much more. We do not always pay attention to this as it is such an automated process in our brains and bodies. We base our actions on our feelings, and how we feel about something and react in a situation can be much influenced by what we consider to be right or wrong, for instance.
Regardless of cultural background, all people share similar wishes related to life and human interaction. We all want to be liked, are grateful for favours, get angry when facing injustice, and want to survive, for instance. The differences are shown in the details and practices. For instance, what we consider favours or injustice, might differ from one culture or person to another.
