I watched as my little brother was cahught in the act. He sat in the corner of the living room, a   21   in one hand and my father’s hymnbook(赞美诗集) in the other. Hearing my father coming, my brother  22    it slightly. He sensed that he had done something   23  . I saw  he had  24    my father’s new book and scribbled(乱写)on the first page in pen. Now,  25    at my father fearfully, we  26    waited for his punishment.My father    27   his book, looked at it, and then sat down without saying a word. He was a clergyman and the holder of several degrees. For him, books were knowledge, and yet, he    28   his children.Instead of  29  my brother, he sat down,   30   the pen from my brother’s hand and wrote in the book himself, “John’s work. 1959. aged three.”

The years and the books came and went. Our family   31  what all families go through. We   32  knew our parents loved us and that one   33  was the book by the piano. From time to time we   34  open it, look at the scribbles, read my father’s expression of love and feel   35  .

Now I know that through this   36  act my father taught us how every   37  in life has a positive side-if we are   38  to look at it from another angle. But he also taught us about what really matters in life:   39  ,not objects; tolerance, not judgment; love, no anger. Love is at the very   40  of a family.

When thinking about these, I smile and whisper, “Thank you, Dad. ”
