When I was a little girl, I found love in a box all because of a class assignment. On a Friday night I   36  at dinner table, “My teacher said we have to bring a box, a special box, for our valentines (情人节) on Monday”.
Mother said, “We’ll see,” and she continued eating.
What did “We’ll see” mean? I had to have that box   37  my second grade Valentine’s Day would be a disaster. Maybe they didn’t love me enough to help me with my   38 .
All Saturday I waited   39  and with Sunday arriving, my concern increased, but I   40  an enquiry（询问）about the box might   41  anger or loud voice, for in my house children only asked once. More than that   42  trouble.
Late Sunday afternoon, my father called me into the kitchen. The table was covered with colorful   43  of different kinds. A (n)   44  shoebox rested on top of it.   45  flooded through me when Daddy said, “Let’s get started   46  your project.”

The holiday party arrived, and my classmates put cards, and presents into the valentine boxes. Laughter filled our classroom until dismissal time   52 .
On the way home, I held out my valentine box for the world to   53 . The love that filled it meant more to me than all the valentines inside. The valentine box became a symbol of his love that   54  through decades of other Valentine’s Days. He gave me other gifts through the years, but none   55  compared with the love I felt within the limits of the old, empty shoebox.
