| I never know how well Mother could keep a trust until I was going through her things after she died. I discovered something I had 1 forgotten, something that happened to me as a child. One night, as I lay in bed 2 my sister and I had said our prayers, I recalled the events of the day and how 3 I had behaved towards Mother. "I must make things right before going to sleep," I thought. Quickly I 4 out of bed and picked up a pencil and paper, then tiptoed into the hall. The 5 from the living room shone dimly. I knew Mother was downstairs mending socks. I quickly 6 a note asking Mother to forgive me for being so 7 . I didn't want my brothers and sisters to know our 8 so I added a postscript: "Please don't let anyone see this." Then I quietly moved 9 my parents' bedroom and put the letter under Mother's pillow. The next morning, when I 10 my bed after breakfast, I unexpectedly 11 a note under my pillow. Mother wrote that she loved me and 12 me. This became my 13 of apologizing whenever I talked back or disobeyed. Mother always left a note, but she never 14 our under-the-pillow messages in front of the family. Even when we were 15 , she never mentioned them when we brothers and sister recalled our childhood. When Mother 16 , I had to go through her personal belongings. In her desk was a bundle of notes tied with a faded ribbon (布条). On top was a message in her handwriting. It read,"In the event of my death, please 17 these." I 18 the packet and glanced at the handwriting on the bottom. To my surprise, I 19 my childish writing, "P.S. Please don't let anyone see this. Love, Edie." I gently placed the unopened bundle in the 20 along with other things for the rubbish burner."Lord," I prayed,"make me like my mother." | ||||
