Interpreting someone's behavior solely based on a single action or statement can be challenging, as it might not give a complete picture of their personality or intentions. In this scenario, we can break down the situation into two parts:
"It's irrelevant what you are saying now": This statement suggests that the person believes what you are saying holds no significance or relevance to them at the moment. While it can be perceived as dismissive or rude, it doesn't necessarily indicate that the person is a narcissist. They might simply not find the current topic interesting or relevant to their current state of mind.
Yawning: Yawning can be a natural physiological response to tiredness or boredom. People might yawn even when they are not intentionally trying to be rude or dismissive. It's a reflex that doesn't necessarily have a direct correlation to being a narcissist.
To determine if the person is genuinely rude or a narcissist, it would be best to consider their overall behavior, attitude, and interactions with others over time. Jumping to conclusions based on one instance might not be accurate or fair.
Keep in mind that people can have bad days, be distracted, or simply not be interested in a particular conversation without necessarily being rude or narcissistic. If you find this behavior consistent and hurtful, it's essential to address your concerns and communicate openly with the person about how their actions make you feel. Open and honest communication can help in resolving misunderstandings and improving the relationship.
