I really know what Jamie Cullum means when he sings
...If I ruled the world
Every day would be the first day of spring...It really is like a fresh start. Everything blooms and somehow I cannot pass any trees that are blooming quietly, I have to shout at everyone around me 'oh my goodness look at that!!' And those priceless surprised faces expecting something really exciting suddenly looking that direction for a few moments, until they turn grim after realising I am getting over-excited about.. a tree.
