Reactions when you tell people you have Parkinson's Disease?

This is not a question so much as a chance to share experiences. My doctor warned me about the reactions I would get. I am 77 so it is not an early diagnosis. He was right. People have all sorts of ideas about the disease most of which are not accurate. I have mostly only told other medical professionals as it is important in terms of what I am taking and how it might impact other conditions I have. The nurses' reactions are sometimes shocking. "Oh I am SO SORRY. My grandpa died of that" and similar. I really get offended and correct their thinking. I have told few friends and mostly just family. Do other PD patients get those kind of reactions? I find it easier not to tell people now that the tremor is controlled. Any input on this.
