Everyone knows that sneezing or coughing is one of the precursors of a cold, so Italians are particularly sensitive to it. In Italy, if someone sneezes or coughs, people around him will immediately say to him: Saludo! I wish you good health! Because I am afraid of catching a cold, I should give them my blessing. In addition, because sneezing or coughing in front of others is a very annoying thing, people who sneeze usually say sorry immediately. This is also an apology for your impolite behavior.
There are many customs in Italy, some of which are really unimaginable. For example, in Italy, it is best to ask more than four people, or even more. Italians are polite, so they don't know how to refuse others. They think it is very impolite to refuse others. So even if I don't know the route, I will definitely point out a way to reply. On the contrary, it makes many people get lost easily, so it is best to ask more people to avoid making mistakes.
Another point is that their concept of time is not strong. This may also be related to their democracy and freedom, and they have insufficient control over the concept of time. Generally speaking, it is normal for them to be more than ten minutes late for dinner. Can they use it? Traffic jam? That's the way to prevaricate. This is actually a rude behavior in our country, but they are commonplace.
To sum up, it is very important to do as the Romans do. People in Italy are already familiar with customs, so when foreigners like us go, we should know the local customs in advance. Do not sneeze or cough in front of others without apologizing.
