Three months passed since I got an electric teeth brush. I thought it was only one month or so, but the indicator that announces the time to change the brush head was flashing. I can’t count my brain’s time flow. I wondered we would welcome the last day of our life like this brush head. I had natto, egg tofu and rice for breakfast. Then I ate the half of mixed fried bowl and the three-quarters cold noodles that were leftovers from last night. It was okay. I was able to save money, anyway.
