You sound better. Must have got some much needed rest.
You are correct about the MLCers memory - it is like swiss cheese, so many holes. It is a good thing to use a written form of communication to have a chance at jogging her memory back. She may get angry because she doesn’t remember and is hidding it, or she does realize how forgetful she has become.
It is very sad to see the forgetful shell of the person you once knew.
It was nice what the doctor told you and very true - Mom you’re doing good.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
