Directions: Read the following passage. Answer the questions according to the information given in the passage.
I remember a day 17 years ago quite well．That day，our twin sons，Chad and Brad, loaded their car and left home to go to college．I realized that our dinner table would soon become a “table for two”. Sure，the boys would come home on the weekends, but even so, I knew our family life would never be exactly the same again．
Before leaving, the boys walked around each room of the house to make sure they hadn't forgotten anything they needed. We all walked outside．Chad and Brad gave me big hugs and quickly got into their car． I waved as they drove away．When I couldn’t see their car any longer，I began to sob. My husband Roy tried to comfort me, but I could see grief in his eyes, as well．
There are many parents who would experience this period．Bittersweet feeling will be present．While the parents feel pride and joy for their children，they will also feel a sense of grief．Painful moments fill their minds．While I can not adequately explain the feelings，I can still remember how I felt when we began that new chapter in our lives．
As time went on，Roy and I are now accustomed to our table for two and we enjoy our lives together．As an added bonus，“dinner for two” is much more affordable than dinner out for an entire family．I have to admit I still miss our children and the old times we had together． But I have to say I enjoy the time I spend with my husband more than ever before．
Roy and I have always enjoyed each other's company，but after the children went to college，we found a great amount of strength in each other．Some things have changed over the years．Our love for one another has grown stronger with each passing day．Together，Roy and I are now doing things we never dreamed possible．Our children oftentimes talk about how we are busier and happier than we have ever been before． Could it be because we fell deeper in love as we spent quality time together at our table for two?
