I didn't particularly want kids at mine, either. But, not being a parent, I did not realize there was such a thing as "teenagers you dare not leave home alone even for a day." Several of them, apparently.
If it's any consolation -- and I know it's not -- mine came off like clockwork. It was a small affair, but I wanted it to be just so. And it was. First time in my whole life I've done a grownup thing in a grownup way and not somehow bollixed it up.
First and last time, I'm guessing.
