Reading your vows from paper.
Skipping traditions you don't care about.
Having both parents walk you down the aisle.
Having nobody walk you down the aisle.
Not changing your last name.
Actually enjoying your ceremony.
Laughing during your vows.
Crying before you even get to your vows.
Changing something because it doesn't feel like you.
Whenever any of us mess up, I'll take the blame.
