There are, it has been said, two types of people in the world. There are those who, when presented with a glass that is exactly half-full, say: this glass is half full. And then there are those who say: this glass is half-empty. The world <I>belongs</I>, however, to those who can look at the glass and say: What's up with this glass? Excuse me? Excuse <I>me</I>? <I>This</I> is my glass? I don't <I>think</I> so. My glass was full! And it was a bigger glass!
