Dollar Dance
"As far as the wedding day, we didn’t participate in the dollar dance, although we considered it. I’m pretty introverted myself and can’t dance as is, so we elected not to. We also chose not to smash cake in each other’s faces…to each their own, but to us just seemed like more of a mess than it was worth."
Why? Because they don't want to follow every standard traditional thing?
If someone tells me that they don't understand some tradition a take them as an illiterate person. You don't need to follow, but understand? Just research it.
You can choose what you want.
