Sometimes I really wonder whether there is love between my parents. Every day they are very busy making money. They don’t act in the romantic ways that I read about in books or I see on TV. In their opinion, “I love you” is too much to say.
One day, my mother was sewing a quilt (缝被子). I quietly sat down beside her and   【小题1】  her.
“Mom, I have a question for you,” I said, breaking the   【小题2】.
“What?” she asked, still doing her work.
“Is there love between you and Dad?” I asked her in a very   【小题3】  voice.
She stopped her work and raised her head with surprise in her eyes. But then she bowed her head and continued to sew the quilt. I was very   【小题4】  then because I thought I had hurt her.
It seemed like a very long time before my mother started to speak again. “Susan,” she said thoughtfully, “look at this thread (线). Sometimes it   【小题5】 , but most of it disappears (消失) in the quilt. The thread makes the quilt strong and durable. If life is a quilt, then love should be a thread. It can   【小题6】  be seen anywhere or anytime, but it’s really there. Love is inside (在里面).”
I listened carefully but I didn’t understand   【小题7】  the next spring. My father had a stroke (中风) and   【小题8】  walk by himself anymore. After that, my mother   【小题9】  my father walk outside every  day. Along the country road, there were many beautiful flowers and trees. The sun gently glistened through leaves. They two, hand in hand, walked slowly. To me, that was   【小题10】 picture in the world — that’s a picture of love.
They still don’t say “I love you” to each other. But I know they have deep love for each other. I used to think love meant flowers and sweet kisses. But actually, love is just a thread in the quilt.
