Our family has an aging grandmother in nursing home. She has advanced dementia and originally refused to go to a home but after being in a hospital after a fall, the doctor, seeing her demential state, agreed to send her to physical therapy/rehab and then onward to a nursing home. Anyway, my question is: every once every few days, my grandma will have the home call us and she'll want to talk to us and ask that we come pick her up immediately. She'll say things that she's taking part of a conference in some foreign country and now that it's over, she needs to be picked up. Or she'll say she's stayed at this nice lady's home for a while now and she has to go home because she doesn't want to overstay her welcome. She says she'll wait for us to come pick her up. What should we say or do in response to this?
