Our Indian culture is really very understandable. In which different importance is given to every relationship. The relationship between brother and sister is on a different level. When they are young, there is fighting. When they grow up, they are ready to help. When they become elders, the relationship between brother and sister is one of warmth for each other. In my opinion, Raksha Bandhan is more special than a festival for brother and sister. @sanjeevm
