This is not a personality trait per se, but a mannerism or behavior which reflects a character trait of — maybe — narcissism/sociopathy. Or a behavior that salespeople use when they’re trying to get a sale. But I think this question is written wrong, because how do we tell personality traits except with behavior?
I don’t trust people who use my name more than twice in conversation. I feel manipulated. How dare they presume to know me so well that they use my name frequently? What motivations do they have with this forced familiarity?
Using my name frequently raises a parade of red flags and leads me to end that conversation very, very quickly.
