When you write your own vows, you can say whatever you want. Traditional concepts can be infused with your own personality, or, you could borrow a team of professional and successful writers who have written some of your favorite lines and lyrics.
From the TV series BONES, said by Angela to Hodgins: “We’re gonna live together, and we’re gonna love together. And we’re gonna have so much fun. And a little pain. And… we’re gonna live a life that’s just gonna make other people die with jealousy, wishing they were us.”
Jack Skellington sang these lyrics in Nightmare Before Christmas: “My dearest friend, if you don't mind, I'd like to join you by your side. Where we could gaze into the stars, and sit together, now and forever. For it is plain as anyone could see, we're simply meant to be.”
