For me personally, people who try to talk at me this way get mentally noted as low-key malicious. Like PUA for the workplace.
Why? Of course, someone might just be toxic. But if someone is actively trying to repair a relationship, wouldn't it be better for everyone to see it as that and try and reciprocate?
If it's noticeable that someone is using an unusual way of talking, the first impression is that it's merely the first, and insincere.
