My aunt called at 5:30 in the morning. She was crying at that time. My aunt said to me “ Your mother called me at around 3 o’clock am. I was surprised. Your mom sounds strange. Your mom doesn’t understand me. I am worried about her.” I said to my aunt “ Thank you very much. I understand. I’ll check my mother’s condition.” My mother will be 85 years old next month. I went to my mother’s home immediately.
I spoke to my mother about what happened. I spoke to my mother about my aunt's concern. And then my mother said , " I never called my sister especially last night . I am not lying". And she got angry. I checked my mother’s phone history. My aunt's name was not registered in the phone history. I'm sure my mom DIDN'T call her. I am relieved to know that my mom doesn't have dementia. She has a memory like that of an elephant.（記憶力がいいという意味にelephantを使う所が面白い） I understand my aunt mistaken my mom as the caller. The phone doesn't show the caller's face so there is misunderstanding sometimes.
