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.

She had been an able-bodied, healthy woman until the accident that caused her to be paralyzed.

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 didn’t like it much, but I did it.
