“The pint’s a pound the world around” is one of the first things I remember my grandma teaching me, when she started to teach me to cook around 5 years old. That and base-12 are the reason why I can make recipe conversions in my head, and why I’m actually a proponent of the imperial system.
And the cast iron pans have to be dried in the oven every time. Don’t let grandma find one in the sink.
