Stealing the spotlight from a couple on their wedding day is the running theme of a lot of wedding drama. It's not polite to celebrate anything other than the bride and groom on their wedding day, especially at a party they paid for. If you really want to propose to your girlfriend or announce your pregnancy and the open bar and built-in party seem like the perfect setting, think again. A couple's wedding day isn't about you--smile, drink champagne, bring a good gift and don't cause a scene.
However, one of the best things about weddings is that you get to celebrate your relationship with all the people you love and care about. When a recent Reddit user consulted "Am I the As*hole?" to ask if he was wrong to tell his transgender sister she's no longer allowed at his wedding because she wants to make his celebration about her coming out, the moral compass of the internet was ready to chime in. Long live family drama!
