My sister called me and said when she went to visit mom she was talking to a "third" person. My sister sat with her at lunch and mom kept talking to someone else, who isn't there. I still want her hearing checked. I've often heard that some people will pretend to hear you and say things that don't make sense because they are embarrassed to admit they can't hear what you said. Now, don't get me wrong, my sister is pretty sure mom is talking to someone who's not there but I think we should cover all bases as well. That's all I know. The doctor hasn't called us back. She is receiving speech therapy. We found that out this weekend.
