On a bus stop, there stands an eye-catching sign. The five bright red characters on the sign: "Mother and son get on the bus" are particularly eye-catching. Not far from the sign, a middle-aged woman with a scarf on her head and a purse on her arm and a child of two or three years old was looking at the big men standing under the sign with puzzled eyes. Why doesn't the middle-aged woman stand at the "mother-child boarding place"? It turns out that it has been occupied by these big men, and there is no place for her. Hey! Strange, isn't this the mother-child boarding place? These big men don't meet the requirements either. We should not stand here! Oh, I see. They must be illiterate. No, look at their costumes. They are all dressed like gentlemen. They shouldn't even know these five words. Then maybe they didn't see it? It's impossible. Those five words are so eye-catching. As long as you have no problem with your eyes, you can definitely see them. I see. They can read and see, but they just pretend not to see. You see, the first person, chubby, wearing coats, trousers and leather shoes that are all international famous brands, seems to be a cadre, and has knowledge and culture, but he still stands at the position where the mother and son get on the bus. He squinted and looked like no one was watching. At first glance, he was a hypocritical person and annoying. Again (reprinted from www.eduZhai.net, China Education Digest.
