My father and I disagreed about curfew (晚间在家的时间). He'd say I was to be in by 9：30 on weekdays, and 11：00 on weekends, no exceptions without my first asking. I told him it made me ____ like a juniorhigh kid. He explained that while a curfew ____ sound like a restriction, it's really about people looking out for one another. The very next Friday after that pretty heated ___， my dad and I had tickets to see our town's professional football game. On that day he was ____ to a nearby city to meet with some major clients and ____ me that his getting home and our leaving for the game would be tight. To make sure we could ____ off the moment he walked in, I got everything prepared. When a half hour had passed from the time he said he'd be home, I understood that he was a little ____. But then, nearly a whole hour passed. I was getting ____. We were going to miss the kickoff! And why hadn't he ____ me and let me know he was going to be really late? As I anxiously ____ the floor, another half hour passed. That's when I got really angry. How inconsiderate of my father! Now we were going to ____ the whole game! When yet another half hour passed, my anger turned to ____. What if something terrible had happened to my dad, like he had a heart attack or had been in an accident, or something? I began to really ____. I'd already called his cellphone about ten times, but no ____. I was beside myself, assuming the worst had happened. Finally, the phone rang, and my dad said ____， “Son, I'm so sorry about the game, but…there was a terrible accident…on the freeway coming home, and I ____ to help… and ended up going to the hospital. I ____ my cellphone in the car, so I couldn't call until now.” I was so relieved to hear from my father and to ____ that he was safe that I actually cried. That was ____ I “got” the importance of a curfew: Checking in! It's about knowing that someone you love is ____. It was one more proof of my father's loving me as much as he does.
