It was the summer of my freshman year of college. Instead of heading home for a nice long   1 , my friends and I had decided to   2  and take some extra courses. We had   3  the top floor of an old house to live in. My bed was   4   into a stuffy (愁闷的)former laundry room and each night was a new   5  in humidity. Still, it felt   6  to be in my own place for the first time. After the first few weeks,   7  , the thrill faded and   8  set in. I found myself sitting alone each night   9  my home and my parents.
My summer holidays had always been a   10  time. I spent hours playing basketball and swimming. I talked to my Mom while she tended her flowers. I   11  helping my Dad drag firewood for the winter. And every night I sat at a dinner table full of delicious food   12  with love while my family filled the room with the sound of sweet   13 . Now I found myself missing them   14  than ever.
Finally when my   15  were at their lowest, I heard a   16  at the door. I opened it and was   17  to see my parents standing there with big smiles to fill my   18  heart and a box full of food to feed my hungry friends. We spent the afternoon eating   19  , and just being together. It felt so good, and I felt so loved.
Victor Hugo wrote that, “The supreme happiness of life is the   20  that one is loved; loved for oneself, or better yet, loved despite oneself.” It was that gift of happiness that my parents gave me that afternoon and every day of my life.
