When they were still trapped in Grimmauld Place, they would dream of their future family: a husband who never yelled at them, who told them all the time how precious they were; a child or two that were never punished for speaking out, that knew their parents loved them; maybe even a dog the family could take on adventures together. They understood why Regulus latched onto the Potter family. That sort of domesticity is so foreign to them, and seems so out of reach.
