Learning experience happens to us throughout our lives. Not long ago I had one that I would like to   36  .
I was going to Marblehead with my sailboat team. The team was racing down the highway at 85 mph   37  we realized we were   38  . Luckily, we saw a rest area ahead. I had a brand-new (崭新) $ 20 bill. I was so   39  because I had never had that kind of cash before. But spending it on  40  seemed like throwing it away. We all rushed into the pizza line.  41  I got a pizza and a drink, and walked to my table. About halfway through the meal, I   42  I had not actually handed any money     to the cashier (收银员). I had just  43  out, and nobody had noticed. I felt terrible.
My conscience(良心) opened its mouth and swallowed(吞噬) me in one big bite. I couldn't   44  over it. I just couldn't go back to the cashier and  45  for my stolen pizza. I was so upset (不安) that I  46  to give myself the pleasure of an ice cream in   47  that someone would say “Hey, Jeff, why don't you use the  48  from the pizza instead of that nice, new $ 20 bill?” I was not so  49  of my cash now.
For the next two years, whenever I was  50  of the “Pizza incident”, I would say to myself “Don't think bout it ”.
I have learned two things from this   51  . Maybe I was a fool for   52  in to my conscience, and being too stupid to appreciate a  53  pizza. But the real lesson is that even if you get away from what you have done, your conscience will   54  up with you.
This reflects the saying “A coward (儒夫) 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  “55” and gone back to pay for the pizza, I would have felt a little uncomfortable about it only once, or maybe twice.
