Inadvertently unsupportive
Nothing a woman needs more than the support of her friends before her wedding. She needs to hear how beautiful she is, how wonderful the wedding will be, and also how perfect she and her future husband are together.
This bride was hoping for some encouragement from one of her bridesmaids that she was looking stunning, but all she got was “I look wonderful.” You don’t want to make a whoopsy daisy like that.
