Of course she was carrying her scissors in her backpack. Where else was she supposed to be carrying them. Why call them hidden?
If you carry a book in your backpack, or a pencil or even a CD player, are you calling that hidden?
I know when I was ten, I surely didn't like to use them little bitty scissors any more. For one thing, my hand was too big. For another, they don't work as well.
Of course, my grandma taught me to thread a needle and do running stitch when I was four, so maybe my grandma was abusive, too...
Original Kamaaina supports 'open carry' for scissors, LOL...
