One of the interesting things I notice about my sister is her ability to accept. She really never asks "Why?" She doesn't engage in navel gazing or self pity. She may not like a person or a situation but she doesn't question what caused her dislike or discomfort.
Since her diagnosis, we've heard her say on a number of times that "I'm just me!" She knows her brain is changing. She doesn't like it but she doesn't fight it. She doesn't grieve or despair for herself because of the Alzheimer's.
This is a gift.
