Yes, a narcissistic person can say "thank you" in response to a favor, compliment, or gift. However, the way they say it and their underlying motivations may differ from how non-narcissistic individuals express gratitude.
When a narcissist says "thank you," it may be more about maintaining their image and seeking admiration rather than genuinely expressing appreciation. Their thank-you might be driven by a desire to appear polite, charming, or socially adept, rather than a heartfelt recognition of the other person's kindness or generosity.
In some cases, a narcissist may use "thank you" strategically to manipulate or control others. By appearing grateful, they may aim to create a sense of obligation or indebtedness in the recipient, which they can later exploit for their own benefit.
It's essential to understand that narcissists tend to view relationships and interactions through the lens of their own needs and desires. Their expressions of gratitude might be insincere or self-serving, but they may still use these social conventions when it suits their purposes.
It's crucial to look beyond just the words they say and also consider their overall behavior and patterns in the relationship to get a more accurate understanding of their true intentions and character. Dealing with narcissistic individuals can be challenging, and it's often best to establish boundaries and seek support from professionals or support groups if you are in a relationship with a narcissist.
