Probably everyone knows the limerick: sweep the snow from your own door, never mind the frost on others' tiles. For a long time, we have often used it to make some kind of judgment or metaphor about the moral behavior of society. If many people in a society are selfish and indifferent, we will use it in a derogatory way to scold the society. In fact, we always hope to raise people's ethical realm.

In America, people don't know this limerick. Not only that, everyone is really just cleaning the snow in front of their own doors, regardless of others on the frost; Nobody sees anything morally wrong with this. After every heavy snow, you will find a busy scene at the door of every household in the United States. People are braving the cold to clean up the snow at their own door. Americans own their homes. They own their land. If you buy a house, then the land attached to the house belongs to the buyer. It is worth noting that almost every home has some public walkway in front of or around it, and these walkways are also private. Americans are sweeping snow from these sidewalks in front of their homes or around them.

One would think that all this snow was swept for their own convenience. But really ask the Americans, he will tell you that it is not for their own convenience, but more importantly for others in their own door do not fall.

What's the mystery?

Legend has it that many years ago, on a snowy day, a young man accidentally fell in front of someone else's house. The fall resulted in a $10,000 medical bill, and the boy suffered a shattered sciatic bone! A few days later, the young man in a wheelchair submitted a lawsuit to the court, accusing the owner of not clearing snow and causing the public sidewalk to hide "organs". The case caused a great deal of controversy. Some say it was an accident and had nothing to do with the owner; Some people say that the young man is negligent, walking is not long eyes, and can blame others for falling? Others said that the owner was too indifferent and lazy, afraid of tired clearing snow, and had to judge him to compensate for all losses...... The court finally ordered the homeowner to pay for all the damage. The court said that no matter how careless the young man is, he will not have the intention of smashing his sitting bone, and the owner did not sweep the snow, of course, the ground is slippery, slippery ground is a potential danger, and the owner of the landlord naturally has the obligation to eliminate the potential danger on the ground.

No matter how controversial, the case has become a century-old wake-up call, every time the snow falls, the first thing Americans think about is how to clean the public sidewalks. We can think that Americans no matter how to clean the snow in front of the door, but also for the sake of their own wallets, rather than out of enthusiasm to "manage" others on the frost, so its moral standards can not be too high praise. But Americans themselves believe that if moral appeals to service are used, fewer people will not only be cleaning the frost on other people's roofs, but also cleaning the snow before their own doors. On the contrary, the use of legal means, not only the latter will be everywhere, but also the former will gradually sprout.
