In general, it is considered impolite and inappropriate for another couple to announce their engagement at someone else's wedding reception. Wedding receptions are meant to celebrate and focus on the couple getting married, and it is essential to respect their special day and the significance of the event.
Here are a few reasons why it's not acceptable:
Stealing the Spotlight: A wedding reception is a celebration of the newlywed couple's love and commitment. Announcing another couple's engagement could shift the attention away from the hosts and make them feel overshadowed on their own special day.
Lack of Relevance: The focus of the event is on the wedding couple and their journey together. Announcing another couple's engagement can be seen as irrelevant and out of place.
Disrespectful Gesture: Making a public announcement at someone else's wedding could be seen as disrespectful and inconsiderate of the couple's feelings and desires for their own celebration.
Timing and Appropriate Settings: Engagements are significant life events that deserve their own time and space for celebration. There are appropriate settings for such announcements, but a wedding reception is not one of them.
Etiquette and Courtesy: Observing proper etiquette is essential during weddings. Proposing an engagement announcement at someone else's wedding can be seen as a breach of social norms and etiquette.
If a couple wishes to announce their engagement to friends and family, they should do so at a separate event or occasion, where the focus can be on their own relationship and plans for the future. Alternatively, they can reach out to the newlyweds beforehand and discuss their desire to share their news. If the couple getting married is comfortable with the idea, they may find a suitable moment during the reception to allow the announcement, but the decision should ultimately be up to them.
In summary, while it's exciting to share joyous news, it's important to respect the significance of a wedding day and not detract from the couple's celebration by announcing another engagement during their reception.
