Yellow flag for the car

I have had trouble with my memory and thinking for several years. I’m 73 now and it seems to be getting worse. I have trouble with all sorts of things these days, especially weekly chores like grocery shopping. I can still drive, but sometimes when I go to the supermarket I’ll forget where I’ve parked the car. It can be very frustrating, and also quite frightening. But what I do now is put a yellow flag on the back of the car, because it’s easy to look at a row of cars and see the little yellow flag, rather than having to walk around looking for it. It’s a simple solution but it has made my life much easier.
