Avoid 'you' statements, such as, 'you should…' or 'you must…'
This can sound accusatory and blameful, which can lead to defensiveness, creating a communication barrier between you and the other person.
Ask for their feedback, for example, 'what are your thoughts?'
By asking the other person to contribute to the conversation and letting them discuss their perspective, you are demonstrating that you are caring and willing to listen.
Listen carefully and repeat back to them your understanding of what they said. This can help the person to feel understood.
