What cultural faux pas should I try to avoid making in Parma?

"In Parma, it is important to be aware of cultural norms and etiquette. It is considered rude to be late for appointments or social engagements, so it is important to be punctual. It is also important to dress appropriately for the occasion, as Italians take pride in their appearance. It is also important to be respectful of religious customs, as Italy is a predominantly Catholic country. Additionally, it is important to be aware of the local customs when it comes to dining etiquette, such as not speaking with your mouth full or eating with your hands. Finally, it is important to be aware of the local language and to avoid speaking English unless it is absolutely necessary," remarked another expat who made the move to Parma, Italy.
