I love it at night. It’s peaceful. And when it cools down I sometimes do some ironing. I don’t really care for it. I work full-time and I am too busy for most housework. I remember the old woman who taught me to iron. I was about 15 and I had to get a job taking care of a woman to make a living. She had been an able-bodied, healthy woman until the accident that caused her to be paralyzed.
The woman sat in an electric wheelchair all day. She could only move her head and arms. She would tell me how to do things. She would teach me in great detail on the correct ways to do things. Her home was perfect and beautiful. She would follow me around in her electric wheelchair to make sure I did everything exactly right. I’m sure she had been a perfect homemaker. She would have me fold(折叠) everything, including socks. I would complain silently and wish terrible things on her. She taught me the right way to make the bed. I know sometimes she’d get frustrated(沮丧) and impatient with me. I knew she wanted to do it herself. But she never shouted or scolded. She only insisted I do it right. I didn’t like it much, but I did it.
Today I can iron pretty well. I know where to start on a shirt and the right way to do the trousers. Now when I think about it, I don’t think she is an old lady. I think she might have been about my age now. Anyway, when I iron, I think of her and silently thank her for all the things I learned.
