I wonder what kind of vetting process the couple went through in the US as well. The story may over-simplify the process.
In Canada, my family knew a couple who tried to adopt a child in the decades ago because of infertility. The vetting process and the paperwork from the government agency was "audacious". They said the amount of red tape was so much to the point that the fertile couples would not adopt locally.
Back in the day, adopting a child from China and Romania was easier than adopting locally.
Plenty of adopted folks have been curious about birth parents as teens and adults. Not sure elsewhere around the world. In Canada, the adoption records used to be closed but have been gradually. There have been cases that the birth parents did not reply.
I practiced classical music 3-4 hours per day. Sometimes in the weekends, too. I played multiple instruments and sang in choir growing up. I enjoyed the work that gave me a sense of accomplishment.
Although I am not a professional musician, the time spent kept me out of trouble as a kid and a teenager. In addition, I learned to win and to lose gracefully, which publicly funded schools no longer teach.
I grew up in the part of Asia that PAL was the standard. Kids beg their parents to buy an NTSC TV so that they can play Nintendo (Japanese version: the red and white one).
