How to act as a plus one at a wedding?

Your main job is to make your host look good and to enjoy yourself without adding stress. RSVP promptly with your dietary needs, and arrive on time. Greet the couple warmly, congratulate them, and keep your congratulations brief if they are busy. Sit where you are told, join conversations gently, and never complain about the food, the speeches or the venue. Follow the couple's lead on dancing, toasts and photo moments. If you do not know anyone, introduce yourself simply and ask friendly questions. Avoid drinking too much, and never make a scene. Thank your host at the end, and send a short thank-you message the next day. Remember, you are there to support your host, not to be the centre of attention. If you are unsure about any custom, ask your host beforehand. A good plus one is gracious, flexible and cheerful.
