The New Baby It's Cold Outside

[rogue06]

I'd also like to point out that back then, someone living at home with their parents was a minor. Adults did not live with their parents. So this girl clearly lives at home, which means she's underage, yet she's at this guy's house unchaperoned, smoking and drinking (or at least trying to drink, given KG's comment). Maybe I'm overthinking it but I've never liked this song.

First, underage back then included was someone who was 20 -- not exactly a "minor."

Second, it was not uncommon at all for a young unmarried woman to still be living at home back then.
