Hi, M.;
For our family, giving them the benefit of the doubt (even a pretend one!) works. I ask the question in a normal voice, using the person's name first, to get their attention. Then if I am not heard I walk to the person, put a calm, open, loving expression on my face, and put my hands on their shoulders, facing them of course, and say their name so they look up. Keeping my hands on their shoulders, I say what I want to tell them, and after I have an answer, I thank them and then take my hands off their shoulders. This way I do not escalate our voices, I do not assume they are ignoring me (even if they are) and I have not given them anything to hold against me. BUT, it is slightly annoying to them to have me be all nice in their face like that, so pretty soon when I begin to talk, they give me their attention so I won't "come over there." In any case, be sure not to be sarcastic at all. This is not what I mean by annoying them, it's just that they will want to get back to whatever they were doing before, and simply learn that it is to their advantage to listen faster. Hope all goes well for you! J.
