Sally Sounding Like Betty?

Did anyone else think Sally sounded uncannily like her mother in some of her complaints? I think, in fact, that Kiernan did an amazing job in that regard. Especially when Sally's on the phone with Don. Her intonations and such were (at least IMHO) spot-on Betty.

It's certainly telling that complaints apt and typical for a bored, materialistically spoiled--but affection deprived--adolescent would be so similar to those of her mother. And while it's no surprise that Sally is mimicking Betty (after all, when Betty complains, she gets what she wants; so if Sally wants something, why not do like mom?), I sure hope Sally grows out of this phase rather than getting stuck in it like Betty.
