signs someone really dislikes you but hides it well, according to psychology

Excessive politeness is a red flag when it comes to somebody secretly disliking you.The politeness essentially serves as a suit of armor for this person:By doing everything “correctly” they can block any real and genuine interaction with you, keeping their mask on socially.As psychology researcher Vlad Niculae found in an extensive study based on behavior of strategy boardgame players: “Players who were excessively polite in general were more likely to betray, and people who were suddenly more polite were more likely to become victims of betrayal.”
