I said that as well but they argue that they must focus on finding a way to sustain themselves and their family and can't take extra responsibilities.
When, I argued that they clearly had time and that taking care of a kid is not rocket science they said I had no idea how may interviews and job hunts they had to go thought just to get by and I said I would help them financially they said they didn't want charity and they could solve this temporary issue they just didn't need an extra worry.
At that moment I realized they just didn't care and stooped trying to argue since the kid was clearly not wanted by them.
So I was able to see that no one wanted the kid just like me. But unlike me the I didn't outright load the boy for something he had no control over :(
