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 .
