Cleaning
Today, I cleaned my room. Of course, I do it frequently. But today, I did it longer than usual. I vacuumed everywhere inside the closet. When I was doing it, a lucky thing happened to me. I lost my nameplate whom is necessary for experiments in July. Finally, I found it in the corner of the closet. I have been thinking that I had dropped it anywhere. So, I was very happy to meet it in about four years. But I reflected that I should put away everything where it should be.
