I ran into a stranger as he passed by. “I’m so sorry!” was my reply. Then he said, “Excuse me too… I wasn’t   41   watching for you.” We were very polite, this stranger and I. Then we went   42   our way after saying goodbye.

But at   43  , a different story is told. How we treat our loved ones, young and old. Later in the kitchen, as I   44   the meal, my daughter walked up to me, very still. When I turned, I      45   knocked her down. “Get out of the way!” I shouted with a frown (皱眉). She stepped away silently, with her little heart   46  . I didn’t realize how rudely I had spoken.

That night, when I lay   47   in bed, God’s quiet voice spoke to me and said, “While    48   with a stranger, you are calm and polite, but with those you love, you are QUICK to excite… Go look around on the kitchen floor, you’ll find some flowers there by the   49  . Those are the flowers she brought for you. She   50   them herself — pink, yellow, and your favorite blue. She stood there quietly and you never saw the   51   in her eyes.”

By this time, I felt sad and small and now my own tears began to fall. I quietly went and knelt (跪) by her   52  . “Wake up, my,” I said. “Are these the flowers you picked up for me?” She smiled, “I found them out by the tree, I   53   them in a napkin（纸巾）, just for you. I knew you’d like them, especially the   54  .” I said, “I am so sorry that I missed them today… And I   55   have fussed (大惊小怪) at you that way…”

And she whispered, “Mommy, that’s OK… I still love you   56  .” I hugged her and said, “I love you, too and I LOVE the flowers.”

Do you know that: if you die tomorrow, the   57   you are working for could easily replace you in a matter of days. But the family you leave   58   will feel the loss for the rest of their lives. And come to think of it, we pour ourselves more into our   59   than into our families--- an unwise investment (投资) indeed.

Remember that   60   =" (F)ATHER" + (A)ND + (M)OTHER + (I ) + (L)OVE + (Y)OU.
