This sounds pretty familiar to me as I've had some communication issues with my sister. When I try to be direct with her about issues, she always seems to get annoyed or even angry, and the insinuation is that I'm weak or too sensitive in bringing it up. However, rather than apologize for my latest misstep in communication, I basically gave her a taste of her own medicine. This means that I was polite but somewhat aloof, I did not call her unless it was to return a call and, even then, I responded via e-mail rather than more directly communicate via telephone. I continued this way for three months until Thanksgiving, at which point I called her to personally to wish her a Happy Thanksgiving. Even though the conversation went well and no issues have come up since then, I've stuck to my approach and communicated with her according to her rules...although not ideal, it keeps us in friendly contact and me from sticking my neck out far enough for her to chop it off. We will never be super close (and nothing in the handbook says that we should be close just because we're related) but we are at least cordial. After years of fighting and stress, this is good enough for me. My warmer, closer relationships are found with different people. She is who she is and there ain't nothing that's gonna change it, at least not by my actions.
