I vouch for that as well. I have seen the dark side of our little ray of sunshine. The "mod power" makes her all demure and sensible,, but alas, we know better..
Seriously though, in real life I am also cheeky, and like to wind people up. I'm sarcastic as well, but I have the charm to get away with it, and that will get me far in life..
It's one thing to wind-up and be cheeky. When people start to get threatening and menacing though, it's just sad really.
