I don't feel it will hurt, but, be on the aware (use your feelings instead of reacting) senitive people, especially if they are in an enviroment that feels unstable or just not comfortable, tend to utilize defense tecniques.
Sometimes they don't want you to figure them out, sometimes they are distant, sometimes they themselve just act out anger in retaliation for feeling these things.
The reason I understand some of these isn't because of book but because I did these things when I was younger. I was angry because I just kept feeling and feeling...nothing made it stop and I certainly wasn't in a position to investigate with the adults in my life or peers. I huffed it on my own, lol, but now at least I can cut through the mish-mash and just call it as I fee it, I suppose

Let me know how it goes!
