Shower

Mom went in to have a shower and shampoo yesterday. I just asked her if she was OK when the phone rang. I hadn't been on the phone for 2 minutes when I didn't hear the water any more. I excused myself and went to check. She was wiping off. I said something about I didn't think she's been in long enough to soap up and she said she probably hadn't. She hair was completely dry as well.
I guess the time has come when I'm going to have to walk her through the steps. I'm going to wash her hair today. I'll just have to do it as fast as possible because it bothers her back, bending over the sink.
Anyone with suggestions would be very welcome to share them.
