6. Bring a present, especially if you want a souvenir.
This one is pretty self-explanatory. Most people have souvenirs/thank-you baskets or something of the nature to thank their guests for coming. Typically, they try to give souvenirs based on what type of gift you brought. Even if there are no souvenirs, it’s nice to bring something — no matter how small — to wish the couple a happy married life.
