Hi, I grew up as an orphan before I was adopted.
I'm so sorry to hear that. Orphans are relatively rare in the U.S. and other developed countries; most kids here can expect their parents to live until they are grown up. I'm sorry to hear this. 
No worries, I enjoy my life now. Is it legal to adopt orphans in the U.S?
I'm not sure. I know if no other relatives step in to raise the child, then they become what we call a ward of the state. But surely there is a process for adoption. I just don't know what it is. Have you ever heard of The Orphan Train? 
The Orphan Train? What is that?
It was a program that transported orphans from crowded cities in the East of the US to new homes in rural towns.
