My wife and I were walking through the parking lot at the supermarket the other day. We noticed a huge truck 1 about a foot into the next parking space. There was plenty of room in its own space, 2 the driver had chosen to park very poorly and made sure that 3 could use the space next to his.
My first 4 was “Why do people act like such idiots (白痴)?”
“What a 5 that people have to do things like that.” My wife said.
I stopped and looked around at the rest of the parking lot. There were a good five hundred 6 and 99% of them were parked well. Their drivers had shown the 7 necessary to park in a way that still 8 other people to park.
“Think about it,” I said. “Only one 9 parks poorly and we start using ‘people' to describe the driver.” The 10 of the matter is that we forget about the thousands of people who behave themselves when we see one person doing something 11.
I've been 12 for many years, and the percentage of good drivers is always 13 than the percentage of poor drivers. “People” don't necessarily drive poorly, but individuals do.
My wife and I almost didn't 14 the many cars that were parked well because the car that was parked poorly caught our 15. It is true that we're far less 16 to see the positive side of things if we keep 17 on the negative. Once we fall into this trap, how many of the wonderful things in the world will we 18?
Our lives are ours to live, and the 19 we see our world is up to us. Remember: the rude person truly is a(n) 20, and not really worth the time or effort we spend thinking about him or her.
