IDK. I did it once with my sister and two cousins in the bathroom but we thought we had to say it 13 times XD It also kinda got ruined because my cousin was like 'Get me out of here!' and he ran straight to the door to get outside. We pulled him back though XD
Yes. In fact, I'm very superstitious about her. For instance I never pass a mirror in pitch black. Their is a mirror near my light switch, so it used to be very hard to get to my bed. Now I have a light up stick thingy. When the batteries die, I'm screwed. Yes I know I have a lot of "that's what she said" moments.
