How do I protect my mother from letting people in our house?
I own a duplex with my mother, she lives downstairs, I up. While she has been diagnosed with AD, she is for the most part okay by herself. I try to get home each day at lunch to break up the day and to check on things. Her judgment is VERY poor. My big fear is that she will let someone in the house. I have posted BEWARE OF DOG and NO SOLICITING signs on all entrance ways, and fenced in the back yard, but I am concerned that if someone rings the bell, she will let them in. I cannot lock her in, but I am wondering if there is a way to keep other people away from the house and to certainly prohibit anyone from entering? I am looking for any ideas/suggestions that would prevent someone from coming to the door to "use the phone" or to "check your meter" as she would give them free access to our living quarters. I have posted notes on the inside of the doors saying "DO NOT LET ANYONE IN" with my work number for her to call. I have informed regular visitors to inform me BEFORE they come, so I can either be there, or leave a note for her that it is okay to let so and so in. I considered disconnecting the doorbells, but I am sure a possible intruder would just knock anyway. Even if not, we have 2 dogs (who would only lick an intruder to death) who would alert her that someone was there. Also with summer coming she will be out in the yard more.
How do I keep people away from Her? And if they do come near - keep them out of the house? She doesn't "get" that someone could want to hurt her.
Any/All suggestions appreciated.
