Why would the parents object to her moving out, at 25?
In the 40s, women living on their own was considered wildly inappropriate and very socially unacceptable. If she was out of her parents' house, its because she was in her husband's house, that's how shit was, then.
Now, others may understand why I sigh and shake my head whenever someone says "THE PAST WAS BETTAR!" No. No, it wasn't. The present ain't exactly a bed of fuckin roses, but its a damn sight better than what it used to be. Economically, maybe, but in pretty much every other aspect, fuck no. The past sucked; the 50s sucked, the 40s sucked, the 20s sucked, the Renaissance sucked, et cetera. The past was crap, learn from it, so the future doesn't turn to shit.
