So I give my girl $3 dollars to hold onto until Sunday. I ask for my money back. She gives me $2 and doesn't say a word. I then say I gave you $3. Defenses: 1) Are you sure you counted right? (So I'm an idiot?) 2) You think I stole from you? (Now I'm wrong) 3) Plain old denial (Can't prove a negative) 4) I would've just told you if I took it (Guilt trip + No you wouldn't) Most logically thinking people would not confess to it, because they know there is NO proof. If you murdered someone and there was 100% NO EVIDENCE, why on Earth would you confese. It's like war, it's always easier to hold you ground, than to invade. Because holding your ground you just have to tie (the other person gives up) or win (the other person gives up and says they were wrong). Where as the other person has to actually prove something that's impossible. One time a good friend and I hid a 30 rack in the woods, to be retrived the next morning, we were both driving our parents car. Next morning it's gone, and the two of us are yelling at each other accusing the other of taking it. Which ever one of us took it, just has to argue and pretend well as good as the other person and it's impossible. Even if you KNOW the other person took it, because you DIDN"T, you can't blame them because then you're the bad guy. After all "he thinks you took it" Seriously. Messed up.
