My husband and l were talking about possible colours because it was time for painting the kitchen again. The children, sat nearby and suddenly shouted, "Not the measuring（测量）stick!”

    The measuring stick isn't a real stick but the kitchen side of the door between our kitchen and the dining room. Along the edge we have    each child's growth by making a mark showing his or her     on every birthday. Over the ten years so many     pens, pencils and markers were used that the door came to be    like a painting.

    Names and dates    different hand-writing, and I can    by the script(手迹)who measured whom. An eight-year-old brother measured his three-year-old sister, a grandchild measured her grandmother, my husband measured me. At parties, when this door swings, friends stop to      the names and dates. When we ask if they would like to leave their marks, they usually had a smile.
