Yeh I see where you're coming from with that, but I don't think she'd see it that way. She might be scared, cause she won't realise you're showing her that you WON'T actually stab her.
Don't be annoyed with me for bringing it down, I just think you'd get into trouble for it. They won't see what you're trying to prove/say, just that you have a knife-thats what I'm guessing anyway.
Please don't be upset.
I'm just trying to help.
