| Learning experiences happen to us in our lives. Not long ago, I had one that I would like to share. I was going to Marblehead 1 my sailboat team. The team was racing down the high-way 2 we felt hungry. Luckily, we saw a rest area ahead. I had a brand-new (崭新的) $20 bill. I was so 3 because I had never had that kind of cash before. But spending it on food seemed like throwing it away. We all rushed into the pizza line. 4 I got a pizza and a drink, and walked to my table. About halfway through the meal, I 5 I had not handed any money to the cashier (收银员). I had just walked out, and nobody had noticed. I felt terrible. My conscience (良心) opened its mouth and swallowed (吞) me in one big bite. I couldn't get over it. I just couldn't go back to the cashier and 6 my stolen pizza. I was so upset (不安的) that I refused to give myself the pleasure of an ice cream for 7 that someone would say, "Hey, Jeff. Why don't you use the change from the pizza instead of that nice, new $ 20 bill?" I was not so proud of my cash now.. For the next two years, whenever the "pizza thing" came to my mind, I would say to myself, "Don't think about it…" I have learned two things from this 8 . Maybe I was a fool giving in to my conscience, and being too stupid to have a free pizza. But the real 9 is that even if you get away from what you have done, your conscience will catch up with you. This goes with the saying, "A coward (懦夫) dies a thousand deaths, a hero dies one." I was a coward and have felt terrible 10 at least a thousand times. If I had been a "hero" and gone back to pay for the pizza, I would have felt a little uncomfortable about it only once, or maybe twice. | ||||
