Learning experiences happen to us throughout our lives. Not long ago, I had one that I would like to __16__. I was going to Marblehead with my sailboat team. The team was racing down the highway at 85 mph __17_ we realized we were __18_. Luckily, we saw a rest area ahead. I had a brand-new $20 bill. I was so __19_ because I had never had that kind of cash before. But spending it on __20__ seemed like throwing it away. We all rushed into the pizza line. __21__ I got a pizza and a drink, and walked to my table. About halfway through the meal, I __22_ I had not actually handed any money to the cashier. I had just __23__ out, and nobody had noticed. I felt terrible. My conscience (良心) opened its mouth and swallowed me in one big bite. I couldn’t __24__ over it. I just couldn’t go back to the cashier and __25__ for my stolen pizza. I was so upset that I __26__ to give myself the pleasure of an ice cream for __27__ that someone would say, “Hey, Jeff, why not you use the change __28__ the pizza instead of that nice, new $20 bill?” I was not so __29__ of my cash now. For the next two years, whenever I was __30__ of the “pizza incident”, I would say to myself, “Don’t think about it…” I have learned two things from this __31__.

This reflects the saying, “Coward (懦夫) dies a thousand deaths, a hero dies one.” I was a coward and have felt terrible about that incident at least a thousand times. If I had been a “__35__” and gone back to pay for the pizza, I would have felt a little uncomfortable about it only one, or maybe twice.
