When I was younger, I subscribed to this theory on an almost daily basis. As a result I was mildly disliked by many, passionately despised by some but grudgingly respected by all.
As a lippy teen, I won debating and speech competitions on all sorts of inflammatory topics, even suggesting that with the development in reproductive technology, we could get rid of the male species all together and all (well, half of us) be better off as a result.
As I've become older, I've learned to appreciate that all opinions are valid, some are best kept to oneself and there is never a clear-cut "right" or "wrong".
Life experience has also taught me that opinions are wasted on those that don't put their money where their loud mouth is and do something about making the things they feel strongly about in theory turn into a reality.
As my work hours have got longer and my lifespan shorter, I've had less time to act on the things I believe in, and in a chicken-and-egg situation I've also become more ambivalent about them too.
Once upon a time, I was all across the Government's budget announcement like a rash, eager to find out which sectors of the community were getting what and waxing lyrical about the perceived injustices of those I felt were missing out.
This week, I didn't even read the bullet point budget highlights. What's the point? Change will happen regardless of what I think about it, so why think about it?
This sort of attitude will no doubt generate a bunch of opinions more passionate than any I might have, but I suspect there will be more people who agree with me entirely.
What Aaron Gilmore did or did not say to a waiter - although essentially of very little national significance - has dominated headlines and sold far more newspapers this past week than budget decisions ever would or could.
If I was to volunteer an opinion, it would be that most people feel like they can't change the world they live in, so they might as well just be entertained by it, instead. Next time someone says "so, what do you think?", I really am going to have to answer honestly and say that, quite frankly, I don't.
