My (R?)AH is currently in rehab and he would call everyday and at any time. I told him the times he could call (or that we would answer) saying it was disruptive to what we needed to do here. He has always been disruptive. Anyway, he was not happy about it, but has been complying so far. I still got an earful when we once didn't answer during the allowed time, but then I just hung up on him and haven't spoken on the phone since. Which frankly, is ok with me.
