THENI: Married the wrong girl? At least two grooms in Tamil Nadu can blame it on a power cut. A black out at a crowded mass marriage venue here at an auspicious moment when about 40 grooms had to simultaneously tie the 'mangal sutra' around their bride's neck led to a mix up with two of them missing the target. Veerachamy, instead of tying the mangal sutra to Subbulakshmi, the bride, tied it around the neck of her friend, who was standing near her. Similarly, Balamurugan tied the sacred thread around another girl's neck, instead of Sivakami. The mix-up which took place at the Sri Subramaniaswamy temple complex at Periyakulam, however, was soon detected. All ended well as elders, in a quick damage control exercise, removed the mangal sutras and made the grooms tie the tread to the right brides after a 'parikara pooja' (pooja for making amends). Temple officials said as all the couples had gathered along with their relatives and their friends, leading to overcrowding on Wednesday night.
