fully putting clothes into his bag .I coughed uneasily. Finally 41 that I was there ,Rocky turned toward me with a sad smile.
“I’m 42 tomorrow ,” he said.
“I know.” My 43 was almost a whisper（低声）.I was 44 at myself for being so weak ,but I wasn’t about to cry .
“My 45 is early ,so there is still 46 time to come to the airport,” he said .Seeing the 47 look on my face ,he quickly added, “I promise(答应) I won’t leave without saying goodbye.” tried to say 48 ,but didn’t . It’s always 49 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 50 .
I remember the day he taught me how to ride a bike . 51 I thought he was always right behind me ,holding the seat to keep me from 52 .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.
