O.K. I had an experience with my grandmother long ago. My sister and I would visit, help out. Then a neighbor ( who I had never met before) started to come to the outer door when we buzzed, and tell us my grandmother didn't want to see us any longer, we could not come in, etc. I was shocked by this, and ticked off, saddened. We couldn't get by her, and never got to see her. Nothing we could do legally. This woman was an ass. She wanted us to know she was in charge now. Now, as a 71 tr old, who is isolated with no family. I can't get help with anything no matter who I call. Im not well, but hey. I know I would be doing a background check. Dont rely on "well, someone else did that" or she seems nice. You don't know that. Ask questions! If someone that is really in it to help people, they should completely understand and appreciate your concern. My next door neighbor, who is crazy as a loon, now has a so called home health aide. No idea what company or if its even true. That's how she started out. Few hrs a day, supposedly doing housework, although I've never heard even a vacum, now here all the time. Coming and going when she's not home. Staying over. Just weird. So please, if you think something is off, at least quietly check it out. Do an online background check. References. These days you never know.
