Short-term memory problem

About 45-55 minutes ago I told Kate that we should dress for the funeral of a church friend before going to lunch. She had been outside working and was a mess. She thought my idea was a good one. When she had dressed, I told her that I thought we should go to Panera to save time before the funeral. She had completely forgotten that we were going to the funeral. She said, “Well, I can’t wear this to a funeral.” Then she went back to her room to change. Now we have even less time to dress before the funeral. It is now 1:07, and the service is at 2:00. This is the kind of thing that is becoming a daily occurrence. Even though I know that her short-term memory is going fast, it never crossed my mind to remind her.
