Yu looks like enjoy her rihab.

Today, I have brought a paper of Hiragana words. Hiragana is the Japanese originated vocabulary to make our communication much better. When I held our it, by gesture of thumb, she shown the woman next to Yu's bed. ( Yu is not in the private room but in the quadruple room. ) And pointed the paper slowly. I folllowed her finger, they are  Ho...Ke....Te...Ru.  It means she has a symptoms of dementia. Added,as you explained,  she pushed the unnecessary nurse call many times and said loudly. I never expected this paper would be used for our private talk.
