     We have two dogs and offer them good food and a comfortable bed. However, they always try to

run away. One day as I was walking them along the river, Cady broke away from me. I called for her to

return, but she didn't. I got unhappy and didn't run after her.

     That afternoon I picked my daughter up from school and I told her that Cady might be missing. "If she

has done something wrong, I will not be paying her fines this time," I said. My daughter asked for the

reason. I insisted that I would not keep a disobedient (不听话的) dog.

     I took a glance over my daughter. It seemed that the thought of losing the dog was very painful to her.

I think I have given Cady a good living environment. If she is silly enough to leave all that behind, then

"bye-bye" is my attitude.

     In a warm and tender moment that brings tears to my eyes, my daughter said, "Dad, you don't

understand.  Cady is not pretty and not even well trained. If she is missing, no one will adopt her. That

means she will die."

     Then I remembered that the reason why I kept the stray (流浪的) dog in the first place was that we

could not find a home for her and did not want her to be destroyed. My heart softened.

     As we pulled into the driveway, there stood Cady in the backyard with a lovely expression. My

neighbor told me that she was clever enough to find her way back. My daughter jumped with joy.
