This tradition started so the groom would not be able to change his mind.
Today - Although arranged marriage are not common, many still continue this tradition. They find it exciting and memorable. In some countries, they believe that the marriage won't last long if they saw each other before the ceremony.
Opening umbrellas indoors

Opening one indoors or under a shade would often offend the God of Sun and would rain the person with bad luck. In the 18th century in London, waterproof umbrellas were invented and they were large. Opening it inside could cause injury or breaking furniture inside which could result to anger and arguments among family or friends.
Today - we still follow this superstition and still believe that it would bring bad luck.
