What should I do

So you're just gonna let her sleep in the streets?!

If you're thirteen I believe it's your parents choice not yours.

And 당신 think anyone on here is going to help 당신 with that problem?
I doubt that...

Um... your room, maybe? Unless 당신 want your room to yourself. In which case, your sister and (Im assuming its male) nephew will live on the street.

I don't think it's YOUR decision, coz you're like...Friggin' 13. Meaning 당신 live with your parents. Meaning, it's THEIR decision.

Why should I even answer this, considering all the "questions" 당신 ask all just seem to be means of getting attention? I don't give a damn about all the angsty things that may 또는 may not be going on in your life.
