My devout Catholic MIL's husband died five years ago. Since then, she's moved 30 miles away to live with us so that we can care for her. Our local parish's bulletin lists a memorial mass for a man named the same as her deceased husband. She's fixated on going because she believes it will be a memorial for her husband, even though she is in a different parish now and some years have gone by. I can't stop her from going, even though I explained that I don't think this mass will be for her dear, missed husband. My MIL still drives. I'm just thinking that -- since my MIL is dead-set on going -- my husband should go with her, to help her deal with any feelings that might come up. He thinks that he should not go, so that she can be confronted plainly by her misunderstanding. Thoughts?
Can you ask the priest to talk to her on the phone to prevent this from happening? He can tell her that he was calling to let her know this was for another parishioner with the same name as her husband, and he knew that would be confusing, but he wants to avoid any embarrassment by letting her know ahead of time.
In the mean time, throw away the newsletter, cross it off the calendar, and maybe she will forget the date! If she does not, you can use what is called "therapeutic lying" and tell her her husband's service was cancelled, that someone called to tell you this morning before she left. This prevents her from being hurt spiritually and emotionally, and is the merciful thing to do. It is a form of "therapy" or treatment for demented people, and I believe God is pleased when we protect our elders instead of letting the chips fall where they may.
In other news, your MIL does not need to be driving if she makes such poor decisions. Contact her doc and ask him to trigger a notice to the driver license bureau. They usually send a letter asking the person to get an assessment from a doc in order to keep their license. Doc can then ask the appropriate questions and see about an early diagnosis of dementia when it can be treated and progression slowed.
