Same here.As a child I watched Neil Armstrong step upon the Moon. No historical event I have witnessed since has topped that moment so I am not really awed by anything..
Of course we are seeing history being written around us all the time, locally and internationally, but the import of what we're seeing often isn't obvious until some time later. Sometimes seemingly big things don't have the impact we thought they might have and equally true almost insignificant seeming events can have big ramifications like a ripple effect.
I think the moon landing looms particularly large because within a few short years it wasn't followed up as many of us had expected and hoped.
It's also true that history is full of moments and events thought significant and amazing by those who witnessed them, but now are only text in a history book to successive generations. I know how many of my generation feel about the moon landing (for example) or the death of JFK or whatever, but to a lot of the younger ones today I don't think it even registers.
This weekend Osama bin Laden was killed. If it doesn't have a significant effect on terrorism (even if not immediately) then it won't really mean anything in the long run. In the short term it's a big feather in Obama's cap and a raspberry to Republicans and neocons.
A royal wedding? Please, who really cares? And it won't mean anything unless they go on to be King and Queen and they do something notable in years to come.
