After my husband died suddenly from a heart attack, my world crashed around me. I was overwhelmed (不知所措) with the   小题1:  of earning a living,   小题2:  the little children.
One  小题3:  evening I came home from work to find a big beautiful German shepherd (牧羊犬) on our  小题4:. This wonderful strong animal   小题5:  to enter the house and make it his   小题6: . The children took an instant liking to “German” and begged me to let him in. I agreed to let him sleep in the basement until the next day,   小题7: we could inquire around the neighborhood for his  小题8:. That night I slept  小题9:  for the first time in many weeks.
The following morning we   小题10:  to find German’s owner, but with no results. On Sunday I took the children on a picnic and we drove off without him. When we stopped to get gas at a local station, we were   小题11:  to see German racing to the gas station after us. 小题12:  was he going to be left behind.
On Monday morning I let him out for a run when the children got ready for school. As evening came and German didn’t appear, we were all   小题13: . The next Friday evening, German was back on our doorstep. Again we took him in, and again he stayed   小题14:  Monday morning. This pattern repeated itself every weekend for almost 10 months. We grew more and more   小题15:  of German. We stopped thinking about   小题16:  he belonged — he belonged to us. As German became part of the family, he considered   小题17:  his duty to take up his position by the front door and remained there until the morning.
Each week, between German’s visits, I grew a little stronger, a little braver; every weekend I enjoyed his   小题18: . Then one Monday morning we   小题19:  his head and let him out for what turned out to be the last time. He never came back. I believe German was sent because he was needed, and because no matter how   小题20: and alone we feel, somehow, somewhere, someone knows and cares. We are never really alone.
