Come semi-finals in any given contest or sporting event, there are 4 contenders. 2 of the teams battle each other, and the other 2 compete against each other. What are the usual reactions of the losers of these rounds? They are devastated, depressed, sad or what have you.
Then here comes the battle for 3rd place. The winner of this round celebrates, while the losing team who landed in 4th place is heartbroken. At the finals, the winner or champion rejoices, while the 2nd placer is miserable.
But why are the odd placers (1st and 3rd) the only ones having a good time? Why are the even placers (2nd and 4th) cheerless? They all managed to reach the final 4 spot of the competition, they all got their places, they all deserve an applause; yet some are unhappy - the evens: they are odd.
