Let her lie there. Let her fee you holding her and make her feel secure. When she wakes up tell her that she needs to tell a) her parents and b) the police.
Say that you will go with her if she wants. This kind of thing is unacceptable and those boys need to be taken off the streets. If she is asleep now then you have already made her feel better by being with her because generally we only sleep when we are relaxed, so good job there.
But in the morning you need to get her to tell people. I hope she's saved the messages they sent her as they can be used as evidence against that gang. Good luck man - aren't some people in this world just sick?
Probably call the god damn cops. Or get your own gang to take care of this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
