.... and why it is called the long goodbye.
My first advice mental is don't worry about the list or days, months, or numbers. Reality orientation doesn't work. Mom's response was her cover because she's losing those details. Just enjoy the moments that you have. Slip into her world and find a reason to smile and laugh. I have found that when I have no expectations it goes much better. My daughter, my Mom, and I enjoyed going through her scrap book and photo album the last time we were there. My daughter's boyfriend caught a great photograph of the moment and I will cherish it.
I see Mom and Dad every two to three weeks and sometimes I am amazed at the changes I see when I return. You are right Meg, even when told it's hard to visualize the reality until you see it with your own eyes... and sometimes it can be shocking. Nothing to do but go with the flow.
I have my teary moments as well.
Hope your next visit is better Mental
