sometimes it's not getting yelled at.....it's more getting frustrated because you can't get the step right and you've been practicing it over and over and over and over!!! It's a common sight at any kind of dance practice or rehearsal!! That's just part of it.
Maybe it'll send a message to fans about how hard these girls practice and stop people from complaining about how much the dance or whatever sucked!
I think there needs to be more "sad" pictures in the world. Everyone smiling in their pictures paints a false image. Reminds me of Robin Williams' movie "One Hour Photo."
