Hi,
I think this is what the question is referring to
You have to look at things separately so think perhaps about how you would communicate with friends compared to colleagues? Perhaps you have colleagues you get along well with and have similar interests so this may differ the way you interact and communicate with others. Do you use certain terminology or abbreviations that those in a different profession wouldn't understand? For example, a SALT may have different terminology compared to a SENCO? Even though they work towards the same aim, they have been taught in different areas. Affecting the relationships, it could be one professional regards themselves superior to another such as teachers to teaching assistants, or external agencies to schools. How does this change the way you communicate with them?
Looking at cultures, it may be they interpret some body languages different to how we do like looking in their eyes, some may see it as confidence and showing they are actively talking and listening, some cultures can see it as intimidating.
If you are explaining it, it's probably best to give examples like the ones above, I'm sure you have experiences as well to include, then say how such things can be overcome.
Hope it helps
