It is also a good idea to repeat a person’s name back to them by saying something like “It’s nice to meet you, John. ”
For example, some cultures only shake hands with the right hand because the left hand is considered unclean.
If you are unsure about how to address the other person, it is okay to ask them what their preference is, especially in professional settings. You can ask, “What do you prefer to be called?”
Instead of saying, “Your view on renewable energy is completely wrong” consider saying, “Your view on renewable energy is very interesting. I never thought of that angle before. ” You might also introduce the person and name a quality that they possess. For example, maybe they are a computer whiz or great with spreadsheets.
When it is your turn to speak, stay on topic and respond to what the other person was saying. This will show them that you were listening.
For example, you could ask someone to meet you somewhere private like your home if you need to talk about something highly upsetting. This way, if you do show emotions, it will be more comfortable.
If someone is avoiding eye contact with you or seeming to be creating distance, then they are likely uncomfortable. If they are reaching toward you or looking directly at you, they are probably comfortable with you.
For example, talking to your friend about a difficult situation at home might make them feel that you trust them and value their friendship.
