Mom didn't tell us she had dementia. She was articulate and smart and was able to hide it for a long time. In hindsight I probably knew it was happening but I didn't. She was at times mean. And I was mean back. I was never patient and I was rarely kind. I'm so sorry. Now she doesn't know who I am. I missed those years. Anyone else have this experience? It would be nice to know I wasn't the only one who has made this mistake.
