Mom is 85 and obsesses about many occasions and situations. My sister and I try to avoid giving her too much information ahead of time because she will go on and on about what, when and where? Is there a forum on line to help us deal with this behavior. She also cuts up papers, plastic soda bottles and re-arranges my refrigerator when she visits. She lives in the garage apartment on my sister and brother-in-law's property but when my sister goes out of town overnight Mom stays with me.
