Confusion

I don't know if it's because some things have changed (I added a bed to the computer room for when my sister comes) or not, but since last night Mom has been more confused than usual. Last night, when it was time to go to bed, she didn't know where she was to go to bed. She asked if she was going up stairs with me. Then this morning, when it was time to have a shower, she couldn't find the towels or the wash clothes. Those things haven't changed. I think it might be just that some things have changed. That's always hard for her and getting harder.
