From my experience with my mom and others:

This message reflects how they may feel:

Speak a little slower. We all don’t process information as fast as we used to. Maybe their hearing aid isn’t working or there is a lot of background noise.

Accept your loved one’s answers. They may be protecting the feelings of someone else or their own memory.

Never argue with your loved one. They may still know how to “push your buttons” but back away.

Help your loved one retain their dignity. Others don’t need to know their capabilities or shortcomings
