232 thxxx1337 Imagine waiting til you're 20-30 years old before being adopted.
490 Fake_William_Shatner I've been trying to adopt Swedish women aged 21 to 25 for years now. It's just so hard to find a home.
30 [deleted] I'm not sure if they do this in Japan in family life, instead of business, or in other east Asian countries, but in Taiwan, adult males are sometimes adopted to take on inheritances when there is no heir available. They are usually extended relatives. Children are also adopted between related families, male or female, for various reasons, such as infertility or financial instability. One example is one of my uncles who never married nor has children adopted one of my 1st cousins, even though the cousin was full-grown adult at the time. Another example is one of my legal aunts is actually from a further extended family. I could be remembering it incorrectly, but I think she was adopted as a child because the new parents were trying for a girl but had only boys.
