She seems pretty mature for her age. That was pretty nice of her to come out to make sure you werent like shocked or anything. On the other hand, you should calm down and stop being obnoxious.
NO need to report her sex life to the world. That's her private life and for you to expose it to her family and her sibling is COMPLETELY disrespectful, rude, and annoying. Just wait until you see her.
If she doesn't say anything next time you see her, leave it as it is. You'll have sex sometime in your life too.. imagine some little prick told on your parents? Wouldnt you be angry as hell?
I am 22years old now but when I was 13 and my older sister was 16 I walked in on her and her man having sex I ran in the bathroom and my sister came in the bathroom and said sorry please don't tell so I didn't I kept my mouth shut its not up to you to tell her parents its up to her just get over it it happenes its weird and you don't know how to act but then its just something you cant stop or change just hope she smart and takes birthcontrol im sure she does so don't worry shell be fine its her man and they are together wrap it up don't tell on her tell her make sure its safe sex its life.
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.
