I stood in the doorway, watching my elder brother carefully putting clothes into his bag. I coughed uneasily. Finally   36   that I was there, Rocky turned towards me with a sad smile.
“I’m   37   tomorrow,” he said.
“I know.” My __38____ was almost a whisper. I was   39   at myself for being so weak, but I wasn’t about to cry.
“My   40   is early, so there is still   41   time to come to the airport,” he said. Seeing the   42   look on my face, he quickly added, “I promise I won’t leave without saying goodbye.”
I tried to say   43   , but didn’t. It’s always   44   to keep quiet if you’re about to cry. “You promised you wouldn’t cry,” he said to me, thinking that I was close to   45  .
I remember the day he taught me how to ride a bike.   46   I thought he was always right behind me, holding the seat to keep me from   47  . I was happy with this, but he knew he couldn’t hold me up all my life. He told me that one day he would have to let go.
His coughing stopped my thinking. What was left to say? How could I say   48   to the person who taught me everything?
The next morning I   49   , looked at my alarm clock, and realized he had left 50  ago. We never even said goodbye.
Goodbye, Rocky! Although he may have been many miles away, I knew he heard me, even if it was only an answer in his heart.
