My daughter is a performer. I don't know where she got it (honestly). Maybe from her dad who has been known to sing Karaoke on occasion or enter a yoddling contest here or there. It doesn't matter I suppose. I am just reconciling myself to the fact that I will be paying dearly to enroll her in all sorts of dance, theater, etc lessons as she won't be able to suppress her will to show off.
Case in point: We went to a dance competition of my niece's and only after a few dances Silvia decided to take the floor. This is just one of the many video's that we took of her that day.
