Some countries have very strict laws about whether a person can be nude in public, like Spain, and what parts of the body can be shown. In many countries, if a person breaks these laws, they can be charged with indecency (which means that they have acted in a rude way that upsets people). For example, if a man took his trousers off near a school, so that the children would see him, he would be charged with indecency. The reason why a person is nude, affects whether the law says that their nudity is indecent.
