It is called law of the mirror ... and it is totally true, usually, what bothers us in others is just that of our interior that we are denied to see ... well, that begins to ask you, why you are so angry at certain attitudes in your partner, your friends, a co-worker ... you will surely find yourself with an answer, which initially does not please you very much but that will definitely help you to grow as a person ...
"You do not know me, you imagine ... you only see in me, what you are" Alejandro Jodorowsky
