Last Friday my brother and I were driving home and had a fun conversation. So absorbed in our talk, my brother took a wrong turn.
Unfortunately, the wrong turn took us towards a  31  , and we had no way to turn  32  . __33  my brother paid the bridge fee and drove on. He was greatly  34  by his mistake and the needless   35   of $4.
We eventually reached an exit, and as we took it, my brother noticed a young fellow  36  over to the side. He came out of his car and tried to  37  someone. I was busy trying to   38  which way we would go next, but my brother stopped and asked the guy if he needed any  39  And he did. He had a flat tire and needed a tool to get it off.
My brother gave him a wrench（扳手）, and then helped him  40  the flat. The young man said that this had been a  41  week for him: earlier he had gotten into a minor car  42  , and now this tire was flat on his way home from work. But he called us “a breath of fresh air’’ and kept   43   us because he really would have been   44   if we hadn’t come along.
After we had finished the job, he thanked us again and pulled out $20 to give us. “No,” my brother said. “We were never  45  to even get on that bridge. We took a wrong turn. But now we know  46   we did. It was to help you. Thank you for turning our mistake into a（n）  47  to serve.”
What I loved most was  48  my brother throughout this process. He was able to turn his mistake into 49  energy to help others even in a negative situation, which could only come from a calm mind and an open  50  .
