Washing Machine

I noticed that a black ink stain was on one of my co-workers’ shirt. I asked him if he had already known about it. It seemed that he didn’t know about the stain, so he looked depressed to get his shirt dirty. Then, he showed me his hands and started explaining how he got calluses in his fingers. I was surprised to hear that he washed laundry by hand. I knew that he was living alone, so I asked him whether he didn’t have a washing machine at home or not. He laughed at what I said to him and said that he had it. However, he hand-washed delicate fabric.
