Can my 21 year old sister adopt me?

You need to get as much evidence as you can and make sure that you have a stable home environment and present it to the authorities and let them take it from there. If she has any visible scratches of any sort take pictures. As long as you have everything that you need then I don't see why they won't give you custody of your sister.

I hope that it works out.

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.
