Yes, I thought so as well.
My mother was not adopted, but she wound up as a foster child. She was the oldest of 3 little girls when her mother, a grandmother I never knew, died when she was 10. Their dad was unable to take care of them, so they were placed with families in the same town. Not the town, nor even the state, they lived in, but the same town in a nearby state. The two younger girls went to the same family, just a block from where my mother went. The younger one was adopted by that family and took their name. That always pained the older of those two. My mother stayed with her family as an only child, but was never adopted. She went to the Army School of Nursing at Walter Reed Hospital, and thus got her education for free.
