The power two words can hold

Scotland within the next 48 hours faces one of man kinds toughest decisions, Independence or to stay as part of a union with their neighbours England.  This vote was brought up a few years ago by Alex Salmond who thinks he is doing what is best for Scotland by pushing this referendum, he might be right.  People have the choice on the 18th of September, Yes or No, two words people normally take for granted.  Two words, two completely different meanings but also at the same time quite similar, normally we think yes to be a quite positive word, and we normally take no to be negative, but can these definitions be can also be reversed, no can be positive as well as negative, but so can yes.  Whatever you would vote in the situation of the Scots its easy to say now, but when the day arrives will you really feel the same, as someone said, yes or no it doesn't matter which you pick, it just matters on do you feel it is right or wrong.
