Singing Bride
We have been through many awkward moments at weddings, but this is not so awkward, really. There are a lot of worse things a bride can do at her wedding than singing her vows. We are not sure why she decided to do that though, maybe she was a singer?
Anyway, it is not so awkward. Just that, everyone must have been caught off-guard. But maybe the groom really liked the gesture and thought it to be sweet. It is kind of sweet to put your own creative spin to the vows. She must have practised quite a bit for it.
