caer mal

to rub ... the wrong way

Decir lo que piensas, hablar de experiencias personales y no de las narraciones que hagan otros sobre la vida, quiere decir que vas a caer mal a algunas personas.	To say what you think, to talk about personal experiences and not the narratives that others make about life, means that you are going to rub someone up the wrong way.

No digo que si alguien te deja de caer mal, a otra persona también dejarás de caerle mal; sino que no puedes cambiar el hecho de que si alguien te cae mal, entonces a otra persona tampoco le vas a caer bien.	I'm not saying that if you end your dislike of someone, someone else will stop disliking you as well; it's just that you can't change the fact that if you dislike someone, then someone else dislikes you as well.
