Well, would it make you feel better if people stopped asking about her? I mean really, people ask about her because they care or they really do want to know. I don't see how that would be "offensive" in any way. My mom also has a degenerative disease (MS). Sure it isn't Alzheimers, but it is certainly progressive and will kill her one day. It doesn't bother me in the least when people ask me how she is, so yeah, that's a little weird to me that you make a commotion about someone asking and showing that they care.
