your mate/caregiver knows whats going on in our twisted brains. Even now I find myself explaining to my wife and kids, whats up with my latest problem. Our PD is a dynamic, ever-changing disease, and we all mistakenly assume our caregivers some how know all about us. I know I can be down-right scary at times.
everyones level of understanding is different. My wife waits for me to ask for help, my 16 year old daughter knows instinctively when I need it.
All my kids and wife, instinctively grab for me when I am about to take a tumble.
Neither way is wrong, just unique to the person involved.
SO my advice, is to prewarn your care-giver about your problems, or failing that, tell them what was going on as soon after the fact as possible.
