I do. All the time. Like leaving an empty Vegemite jar in the fridge and secretly using the one in the pantry just to see how long it'll take for Iven to cave and admit that it's really empty. Or not throwing away mouldy foodstuffs to see how long he'll keep shaving the mold off the cheese despite the threat to his health. That man really likes to live on the edge.
I've actually had a small experiment going for the entire length of October which I could only just reveal - being that it's now November. For all of October I had the calendar hanging on the back of the toilet door opened to November. Okay, it was an accident but when I noticed what I'd done the next day, I decided to leave it and see how long it'd take for someone to say something about it. I was pretty sure that no one would actually change the calendar because that seems to be my job and mine alone. But I'd notice if they did and the experiment would be over.
My toilet door is covered in cork tiles and cute animal photos. Makes for a more pleasant toilet experience if you ask me.
A week passed and no one said anything. Each day I'd sit on the throne and chuckle to myself about how unobservant my family is. In the second week my cleaning lady told me that it was on the wrong month so I then had to explain what I was up to. She understood exactly what I was doing - providing myself with scientific proof that men are less observant than women. And so far she'd helped out the women's case enormously. We were now at 100% for observational skills.
By the end of the month I'd heard nothing from the male side of the equation. Zip. Zero. Nada. So yesterday I revealed to Iven that he'd unwittingly been a participant in my study. And apparently my observation, that 100% of males wouldn't notice that a calendar was on the wrong month, was incorrect. He had noticed but he'd assumed that I didn't like the October dog as much as the November one. He just hadn't bothered to comment about it.
So my experiment proved nothing except that 100% of males in the household couldn't give a rats about the calendar. And that 50% of the males probably didn't even see it because they rarely bother to shut the door.
Why do I bother?!!
