Wedding season is coming! There are some things that are pretty common knowledge when it comes to etiquette as a guest at a wedding. Of course, ladies should never wear white to a wedding -- the focus should always be on the bride -- you never bring more people than were invited on the invitation, and you should never throw your drink.

Yup. You read that last one right. This poor grandma was only trying to celebrate the bride and groom with a cup full of confetti as they walked out the door but must have confused her cup of confetti with a glass of her favorite beverage.

The good news is...they kissed and made up!
