I am genuinely bewildered as to why you think I want something out of you- it is nothing but the ramblings of a madman trying to justify something to himself.Whatever you say you are not going to get the response out of me that you clearly crave.
As Cougar said, you need to phrase things or explain them better.
For example.....
"I would appreciate no jokes about dementia, as it is touchy subject that's close to me. Thank you."
