Guardians of the passengers

One the way to school, if need to come across some big roads, then it must be very familiar to see this kind of scene.

If you don't know what I mean, just look closer again.

Yes, the traffic police.
We all had read some articles about appreciating the traffic polices. But as I am passing the road, I still forget about how hard they work.
One morning, I was passing the zebra crossing, and I saw a little girl without being accompanied by any adult was crossing the road, too.
That road was really dangerous at that time, because many cars are turning right at there, and when they turn right, they must pass by the road.
Another difficulty for the little girl is that the time for crossing the road is almost over.
She was so small that nobody noticed her.
But the traffic police did.
She raised her right arm to the cars to make them stop, until the little girl pass the road.
I was deeply moved on the other side of the road.
For the first time, I truly realized the importance of the traffic polices and appreciate their hard work.
What they are doing is to put their lives in risk to exchange the order of the road, and the passengers safety.
I want to say thank you to them again, and next time while I pass the road, I will be more careful, keep myself from causing any problem to them.
