You’re asking if we always feel the need to dance when we are happy? Like that’s a bad thing???
We should ALL be so free and joyful in our everyday lives that bursting out into dance and song is something which frequently happens. If you can’t understand that, I truly and sincerely feel sorry for you. You are missing out on a happy life (despite realities that always come our way)!
Well we're kind of wandering off topic here but...Ok. As far as the OP, I simply don't think the video shows what "all weddings should be".
And please don't "feel sorry" for me b/c I don't dance or sing where it's inappropriate. I don't laugh when it's inappropriate, even if I'm thinking something is really very funny. It's just not my way.
