So few days ago I asked is my daughter okay, you consider me a troll. Why?

When she was 13, she asked for a guitar, I bought her used, she now 15 and loves playing it. She may just sit and play for no reason. I don't understand this.
Also I think she is not a virgin. She have some friends and boys included.
And she also paints her hair violet (you know, this fading type when roots are almost natural and ends are violet)

Serious question.

My daughter (seriously, don't ask why) asked me for a guitar few years ago and I bought her used. She loves to play guitar, even even sing. Why?
She is 15 now, her friends bring her for meetings.

Also I'm afraid she is not a girl. She also paint her hair violet and wears violet lenses.

Is this okay?
