The phone call sounds fine. Then, a few weeks later, you learn that the Tuesday cards did not happen, the neighbor who used to walk to the corner with her has not been over, and the lunch with her sister was moved again. Nobody has said anything dramatic. That quiet shrinking of her week is easy to miss from five hundred miles away, because a social calendar is made of small appointments that nobody writes down for you.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Build the list before you need it
Ask her, on a good call, what a normal week looks like. Write down every standing thing: church or a service, a card or bridge game, a weekly call with a sibling, a standing lunch, a neighbor who brings in the mail, a volunteer shift, a hair appointment that doubles as a visit. Add the person attached to each one. A list of six names and four weekly commitments is your baseline. Without it, you can only tell that something feels off, and a feeling is hard to act on.
What to check on each call or visit
Go through the list and mark four things for each item. Does it still happen? Does she still go? Does she still reach out to the other person? Does that person still reach out to her? A commitment she keeps but no longer seems to enjoy is different from one she has dropped. Listen to how cancellations are worded. A specific reason is one thing. Vague phrasing like 'not up to it this week' is worth noting. Notice whether she turns down invitations she used to accept without thinking, and whether she still suggests plans of her own.
Ask the people who are already there
Neighbors, friends and church members often notice first, if anyone is asking. Ask two plain questions: when did you last see her outside the house, and has anyone else been by? Frame these as checking in on the group, not as reporting on her. You are asking people to tell you what they already know, not to watch her for you. If you do not have anyone there yet, start with the steps on Local Help for a St. Louis Parent.
Separate pulling back from a bad stretch
One cancelled lunch means very little. A pattern across several weeks, where the same commitments fall away and nothing replaces them, deserves attention. Pulling back can come from many causes: pain that makes sitting or driving hard, hearing or vision trouble that makes groups exhausting, low mood, or simply losing the person who used to organize the plans. These call for different responses, and you cannot tell which one it is from a list alone. The list is what lets the people who can tell you more ask better questions.
What to do tonight
If you have not written the baseline list, do it now from memory and fill gaps on the next call. Pick the one commitment that most clearly used to happen and find out, by a call or a text, whether it still does. Then write down in plain words when each thing stopped, as close as you can get. Rough is fine. You do not need an exact timeline.
What to leave with the doctor
Bring the list with the stopped items marked. Describe what you have seen, not what you think it means: 'She has stopped going to the Thursday lunch and has turned down the last three visits from her sister. She used to start those plans herself.' Ask whether pain, hearing, vision, sleep or mood could be part of the change, and whether anything should be checked before the next visit. Ask how the family should share what they are noticing, and whether she should hear about it directly.
The point is not to catch her out. It is to notice that her week has gotten smaller while there is still time to make it bigger again, with someone close enough to knock on her door.
