My father enjoys bike riding．Ever since I was little, I’ve always loved going biking with my dad．36 , as I became a teenager, other things began to draw my 37．Suddenenly, It was important to do things with 38．I saw my dad every evening at home．Why did I have to 39 my Sundays to all-day bike trips with him , too? If my indifference（冷漠） hurt him, my father kept 40 , but he would always let me know when he was planning a bike trip 41 I wanted to come．
It was a Sunday morning, and I was in low 42．Two of my friends had gone to the movies without inviting me．Just then my father 43 my room．“It’s a beautiful day．Want to go for a 44 today, Beck?” “Leave me alone! ” I impatiently 45．Those were the last words I said to him before he left the house that 46．
Several hours later, the police called us, 47 us that Dad had a traffic accident．My father’s injuries were serious．It took several days before he could 48 speak．Beside his bed I held his hand gently, 49 of hurting him．
“Daddy … I’m sorry …”
“It’s OK, sweetheart．I’ll be OK．”
“No,” I said, “I 50 what I said to you that day．You know, that morning?”
“Sweetheart, I don’t 51 anything about that day, not before, during or after the accident．I remember kissing you goodnight the night before, though．” He 52 a weak smile．
I felt regretful for my 53 words, for I never wanted him to leave me alone．My teacher once told me that 54 have immeasurable power．They can hurt or they can heal．And we all have the 55 to choose our words．I intend to do that very carefully from now on．
