My paternal grandmother didn't know how to cook when she got married, her mother and older half sister were terrific cooks and somehow she never learned. So my grandfather taught her, she's a good cook as long as she has a recipe and specific instructions. My great grandmother cooked a lot with "a pinch of this" or " a handful of that" and my grandmother couldn't learn that way. She needs precise. 1 tablespoon of this or 2 cups of that. And she doesn't know how to really subsititute for things or omit something.
I take after my great grandmother (who I never met, she died a few months before I was born) and deviate from recipes all the time or just make things up.
I did not get any of the talent of fixing up or creating things (besides food). My Mom is a great one for home improvement jobs, partly out of necessity (being a single mom) and mostly because she likes it. She redid her entire half bath, including replacing the toilet, with minimal help from her best friend.
My brother is a good at making things -he's made a coffee table top, a bookcase, and other things. Plus he's handy with repairs -- and can cook! People think he takes the home repair and building stuff from my dad. Nope, Mom. Although both of my grandfathers were good builders and creators.
Mom taught us how to cook and do laundry and other things. It baffled me to realize when I was out of high school that people my age didn't know how to do laundry or even how to write a check.
When SLNRLBF was here he did most of the cooking. He's a good cook even though he says he's not. And we helped doing dishes.
