March Madness?

I have to admit...I'm a little confused about this whole March Madness deal hahah yes, I know that it is a College Basketball tournament and everything, but to me, it just seems like regular basketball games. People get all excited about filling out these brackets, and the only conversations that I hear at school now seem to be about 'what games won last night' and 'if I'm winning my bracket'...if it makes others happy, that's great! hahah but for me, I don't understand why it is so important! I better learn fast, though, because it will probably be the most talked about topic throughout March...oh gosh haha but to all of you competing with your brackets, I wish you guys the best of luck(:
