The boy who lost the manhole cover put up a sign to remind him that what the two boys did was worth learning?

I think the practice of these two boys is the main reason worth learning. There are the following points.

The loss of the first manhole cover is actually very dangerous.

I believe everyone knows that losing the manhole cover is actually very dangerous. If the manhole cover is gone, this place is a very big hole. If pedestrians keep playing with their mobile phones and don't pay attention to their feet, they are likely to step on the air and fall in. Once he falls in, his life is likely to be in danger. Not only people, but also cars are very dangerous, such as electric motorcycles. Its wheels are relatively small, and it is likely to get stuck or fall in.

It is precisely because the loss of the manhole cover is a very dangerous thing, and the two boys cleverly set up signs to remind pedestrians, or passers-by have lost the manhole cover here. This kind of behavior is very warm and deserves our praise and study. If it weren't for their warning, it is likely that someone will fall in if they don't pay attention, and once they fall in, they are likely to suffer heavy casualties.

Second, not all people are willing to help others.

Many people must be ready to help others when they receive education when they are young. However, after working in the society for a long time, they often see that these things that need help are indifferent. For example, if the manhole cover is lost, it is likely to be seen, but he is indifferent. He feels that this is not the place where he should help, or that others will naturally help. This matter has nothing to do with yourself, that is, the so-called matter has nothing to do with yourself.

In fact, there are many such people. It is because there are so many indifferent people that these two children are extremely warm, which is why I think we should learn from them. It is precisely because this society is indifferent that we need more warm people.

Based on these two reasons, I think what these two children have done is worth learning, and I hope everyone can help in real life.
