What is the first rule of etiquette?

The first rule of etiquette is to make others feel comfortable and at ease. That guiding principle shapes how you greet people, how you listen, and how you behave at a wedding. If you are unsure what to do, ask yourself whether your action would put someone at ease or make them feel awkward.

At a wedding, this means being gracious to people you do not know, thanking the hosts, and not drawing attention to mistakes. It also means being flexible when plans change and not complaining about small issues. Etiquette is not about rigid rules. It is about showing respect for the people around you.

If you are a guest, the first rule also covers your response to an invitation. Reply promptly, arrive on time, and follow the dress code. If you cannot attend, let the couple know as soon as possible. That helps them plan seating and catering. Treat every person you meet, from the registrar to the waiting staff, with the same warmth you would show a friend. That is the heart of good manners.
