Your ceremony doesn't need to be long to be meaningful.
Personal doesn't have to mean serious.
Traditional doesn't have to mean impersonal.
You don't need to memorize your vows.
You can have private vows and still say something to each other during the ceremony.
There is no rule that says you have to pick a bride's side and a groom's side.
Your ceremony can be funny without turning into a comedy routine.
You're allowed to skip a reading, ritual, or tradition simply because you don't care about it.
The marriage license and the wedding ceremony are two different things. One is paperwork. One is why everyone showed up.
Your guests probably won't know what you were “supposed to do.” If something changes, keep going.
