DEAR ABBY >> My oldest sister has it in her head that since she’s home all week, she needs to go out every Sunday. She started calling me every Saturday to invite me to accompany her, which I did a few times. In doing so, I realized she has mobility issues and the beginnings of dementia. She wants to go to these certain places where we would always go. Other friends and family members used to accompany her, but no longer do for liability reasons. Hence the reason she turned to me. Apparently, she refuses to accept her limitations.

My sister should use a walker and no longer be driving but does both. I am afraid and concerned. She keeps calling me every weekend, and I’ve already run out of excuses. I feel terrible about this and don’t know how to handle the situation. I desperately need some advice. She obviously doesn’t get the hints.

DEAR SIS >> Stop hinting. Talk to your other relatives about what to do if, as your sister’s dementia increases, someone has to take her car away. That she wants to get out of the house on weekends isn’t surprising, considering the fact that she’s cooped up there all week.

Contact your nearest senior center and inquire about supervised activities for seniors and transportation options for people with disabilities.

Folks with memory issues also have been known to get on the highway intending to drive to Sacramento only to wind up in San Diego because they lost their sense of direction or misremembered their destination. If necessary, because your sister could be a danger to herself and others on the road, send a letter to the DMV.
