Dance with your wife! You're married now, don't be one of those guys that is too shy and stands on the sidelines watching. Dance with your new wife and enjoy it. *** Celebrate! Don't be shy, go and enjoy this moment!
Eat! Have a good breakfast - if your wedding is in the afternoon, this is probably the last chance you'll get to eat for a long time. And make sure you eat at the reception - it's very easy for the bride and groom to miss out and be starving before the party is over. *** Don't forget to eat. We don't want to faint from hunger during our most important event do we?
