A friend of mine found out she was pregnant a few months after she got engaged. Both she and her fiance grew up in pretty conservative Christian families (in fact, her fiance was in school to become a pastor at the time), so announcing this news to their families was not easy. But they decided that they couldn't keep it a secret -- the wedding was not supposed to happen for a whole year. Thankfully, the families seemed to take it pretty well. It was decided that the wedding date should be moved up so that the bride's belly wouldn't be noticeable in her wedding dress.
Everything was going along smoothly on the big day, until just moments before the bride was about to walk down the aisle. An extended family member approached her from out of nowhere and whispered to her that she should be ashamed and should not be wearing a white dress. The bride burst into tears and ran into the bathroom, leaving the groom waiting up at the altar. Her father told the offending guest to leave immediately. We consoled the bride. She made it down the aisle. They now have a gorgeous daughter who is the light and joy of their lives.
