Seems like a good photographer portraying her...how to say in English...bright and lively (which I guess she is :) ) ? She could like step from her chair right out of the picture...

I don't know what you mean by wrong start... but her arguing... I guess to make up her own mind is important... as part of finding out and further developing and defining herself. And youth may get some credit for not even always doing it as respectfully as we should all learn to be at some point. Encourage her :)... Great you support her so much!
Ps Dancing... Cool! Specific style(s)? Ten years (hobby) salsa dancer myself :)
