[2019·福建省质量检查]My neighbor Orlando is a paramedic (护理人员). He and his wife are some of the nicest people I have ever met. A few  years back we started this sort of “favor war”， where one of us would do something for the other, such as shoveling (铲) his driveway or helping him build a shed, and next time the other would try to top it with another favor.

Yesterday morning there was maybe 2 or 3 feet of snow on the ground and I remembered he shoveled my driveway for me last snowfall. So I took out my shovel and took care of both our sidewalks and driveways because it was my turn to do a favor back. It took a while but I finished and got into my car for work. What I didn't realize was that Orlando had to work that day too.

Fast forward to this morning I got a knock on my door. It was him. He immediately shook my hand and informed me that because I shoveled his driveway and sidewalk for him, he was able to get to work earlier. As soon as he started his shift, a call came through that a young boy was in a medical emergency. Luckily he and his partner were only about 2 minutes away, but the next closest ambulance was in 10 minutes. This kid did not have 10 minutes. He barely had 2 minutes. Because my neighbor got to work sooner, the young boy got to live his life.
