Cultural Tip
In Italian households and restaurants, leaving food out is considered careless because it can attract insects, cause spoilage, or lead to foodborne illness. In many regions, especially in the south, meals are communal and food is often shared, so keeping dishes supervised shows respect for the host and the guests. When speaking to children, Italians often use the infinitive form for gentle commands, as in this sentence.
