There I stood, peeing into the urinal, doing what we men so often do. I was trying my best to use the intense force of my jet to get the detergent cubes to disappear through the grating thing, the metal guard bit. Any man reading this will know exactly what I mean.
Those cubes, they shrink and eventually get down to a size that forces every man in the world to attempt to pee them through the aperture. The feeling of satisfaction when we actually do this is immense, a bit like winning your fifteenth grand slam title or a Grand Prix.
And, as I did this, or failed to, I realised that most women just don't know about this sort of thing. Unless the woman is a toilet cleaner or has an incredibly weird hobby.
Such a simple act, an easy pleasure and no woman will ever get to attempt it. Even if there are females out there who are aware of the existence of these toilet cubes, they'll never be able to use their pee as a slightly disgusting light saber, the way we can.
They'll never know the joy that we used to have when we tried to pee up to the huge record height on the wall in front of the urinals at school. There was always a myth that some bloke, usually a heroic type who left the school a few years before, had managed to pee up to "that mark up there".
There are many things that the fairer sex will never know and never understand; how it feels to get kicked in the balls, the relaxed joy of parallel parking with ease, getting all the credit for standing in front of a barbecue and turning some meat occasionally while drinking beer and chatting to people.
Every single man can feel the pain involved in getting a football or a kick to the bollocks, it's part of our upbringing, yet women just don't have a clue on this one. As I mention it I bet that you, if you possess balls of your own, can feel that tingly and winded pain in the pit of your stomach, but women just screw up their face and think that we're laying it on.
Then they complain about periods, childbirth and the like!
So what else is there that women, or men, just don't know? Comments on a comment please.
