As I posted earlier, upon my arrival I was informed that I was now "one of four" kids and, therefore, not entitled to anything other than what everyone else had. However, the reality was that there weren't four kids living at home at that point. My uncle's daughter had left for college that Fall, and once she was no longer a permanent resident, my uncle and his wife opted to send their Down Syndrome son to an institution in a city two hours away. Their daughter had been his primary care-giver, much more so than his parents, and he was too much trouble(?), too difficult(?), too time-consuming(?) for them to handle without her. They never told me the real reason, and I never asked. He lived at the institution full-time, coming home only every other weekend, until he moved to an adult group home several years later.
Therefore, the only other child living at home was my younger brother. Recall that he was both my biological brother (adopted at the age of three months) and, soon, my adoptive brother as well.
