【Why do we use “How are you?” at the beginning of conversation?】

My dream is to give you the energy all over the world by radio📻There are few people who answers “I am happy” during Covid-19. Because we don’t know what happy is.However, you feel like you can answer “I am fine”, don’t you?😉In my opinion,it might be the most important for us to be fine even though we don’t know what happy is.Because we can challenge what we want to do if we are fine.Then, we might discover what happy is.Now, I have worked in Italy since 2018.My favorite Italian word is “Tutto bene”Let’s enjoy with me😆🇮🇹
