Is there anyone who watched the show very closely? There's one major inconsistency I noticed regarding Lorelai. At multiple occasions it is said that Lorelai had such great potential, that she was an excellent student, that she would follow her father's footsteps to Yale etc. And that only the teen pregnancy was the one issue where she threw her entire future away.
Yet Lorelai didn't get pregnant before 16, I believe in one scene it is said that she was very late state pregnancy so she couldn't attend prom. So she wasn't much older than Rory when finishing Chilton.
Adult Lorelai doesn't seem smart though. She struggles with her management class, she doesn't speak any foreign language (we're been told about Italian, French, Spanish (Café au Lait), German, Latin). She has a poor reading comprehension (struggling with Proust, manuals, fishing books, etc).

So, how was this ever explained in the show?
