The reason why AB blood is annoying

A person with blood type A and B is a perfectionist, so he often feels that what he is doing is perfect, but if something happens, he also feels that the problem is impossible for him.

And the consequence of this self-confidence is: start to constantly pick mistakes on others, even when the state of the matter is not clear, a bunch of complaints, blames, and provocations will sweep through.
