Cultural Tip
In French culture, guests are expected to be punctual, bring a small token (like a bottle of wine) for a dinner, and avoid dominating the conversation. Using the informal structure with a fronted topic and a repeated pronoun is common in everyday speech, but avoid it in formal writing or official invitations where a more polished form such as « Comment les invités doivent‑ils se comporter ? » is preferred.
