I ran into a stranger as he passed by. “I’m so sorry!” was my     . Then he said, “Excuse me too ... I didn’t even      you.” We were very    , the stranger and I. Then we went on our ways after saying     .
But at home, a different      is told. How we treat our      ones, the young and the old. Later, in the kitchen, as I cooked our supper, my      entered, very still. When I turned, I nearly knocked her down. “Get out of the way!” I      at her. She left, with her little heart broken. I didn’t      how hard I’d spoken.
That     , as I lay awake in bed, God’s quiet voice      to me and said, “While with strangers, you are polite,      with those you love, you didn’t do it properly. Go and look right now on the      floor, you’ll find some flowers there by the door. Those are the flowers she    __  for you. She picked them herself—pink, yellow and blue.”

I still      you anyway.” I hugged her and said, “I love you too and love your flowers, especially the blue.”
