Will rearranging an elderly persons belongings cause confusion?

Did your mother enjoy movies? If so, it's worth a try isn't it? - you can always turn it off, or even take it out of the room if it's actively bothering her.

Though your brother's girlfriend might do better to save her money... Still! It's her money! Just warn her she's probably wasting it.

My mother is VERY picky about where her "things' can be placed. She has specific locations for everything from safety pins to soup cans. If I accidently put something in the wrong place, she kind of flips out. As messy and hoarded as her place is, to her, everything is like a big "hug" and everything staying the same makes her feel safe.

BTW, she has a TV in all the rooms but the bathroom, and that's only b/c it's not cabled for one. If your mom liked TV that would be one thing, but she doesn't, so don't bother.

I know it seems weird to us, these quirky behaviors, but we need to respect our parent's "stuff".

I doubt that the Tv will change anything. She will probably just ignore it just like everything else.
Now rearranging an elders pocessions or living areas will cause confusion and distress
