When Scissors Go AWOL

Why is it that scissors never seem to be in the right place? Not in the kitchen drawer, where they're supposed to be, but in the last place you left them. (Which is always the last place you look.) This is a phenomena that has been going on since I was little. Mom would go to use the scissors, and of course they would not be where they were supposed to be. Then I would hear, "Carmen, where are the scissors?!?" To which I would respond, without even thinking, "I don't know!!"
Mom: "Well where did you put them?"
Me: "I didn't have them!"
This would carry on for awhile, Mom sure that I had misplaced them, and me wondering why I always got blamed for the missing scissors, all the while scouring the house to find said scissors. They always got found, and without fail they were exactly where they had been left the last time they were used. (Not necessarily by me.)

Well I'm an adult now, and I have my own scissors to worry about. And they are consistently AWOL. And although I don't have children, I do have a roommate, and when the scissors go missing, the first thing out of my mouth is, "[Roommate] where are the scissors?!?"
