When my brothers and I came back from war we moved back in with my mother, but it was NEVER expected that we would live there forever. Indeed, when I left Grad School no. 1 I didn't go home, but took a bus to Ohio, slept on a friend's couch, and looked for (and found) a job.

Mother said that she'd provide a roof and meals while we were in college, but when we got that bachelor's degree we were on our own! And she held to it, too.
