     I closed my eyes as tight as they could go.

     The lights went off, and I unbolted the door of memory. I remember driving home by myself for

the first time. I looked into the future and imagined that I was walking on the stage to receive my college

diploma. I looked at the bleachers packed with families and friends. I saw my parents smile with pride,

and I looked to their side for Katie and Kevin's approval. But Katie, my elder sister, was not there. I

cou7ld hold back my tears.

     I suddenly opened my eyes and returned to reality. I remember being called out of Spanish class in

 the tenth grade and taken to the hospital to see Katie, who was dying of cancer. Katie's room was

exactly the way she had left it on a Friday night in September, 1993,when she was got into the ambulance. She died just a few weeks in her freshman year at the University of Miami.

    When Katie was six years old, she declared herself old enough to take care of her little sister and

brother, because she wanted to lighten our mother's burden. Katie would always do up my hair and

go shopping with me. She would always tutor Kevin and buy him ice cream as a reward for his hard

work. Clearly, Katie was more than our elder sister.

     A diploma is placed in my hand . "I do !" I cry. Katie said she loved me and hugged me tight on a

September afternoon in 1993. just before I step up my college auditorium stage, I look at the spectators

in the bleachers and see mother, father and Kevin. Katie is sitting right beside them , cheering me on.
