I have old people on either side of me, and you've heard about my neighbors to the right who wanted me to turn off the AC because the noise was deafening.
Last Friday night, when Baby A and I came home, it was around 9PM and I saw a cop car in front of my neighbor on the left's house. She is an old lady in the early stages of dementia. A man in his 40's was living with her and taking care of her and the house up until about 2 months ago, when he had some altercation with the old lady's daughter and moved out. Now she's on her own.
According to the neighbor across the street, the old lady does indeed have dementia and the cop was there to "check on her". When I got home with Baby A from the store this morning, the cop was there again.
